this is largely a response to this joke video matt parker made in 2013 ua-cam.com/video/r7x-RGfd0Yk/v-deo.html
hmm
We could always try reeducating the populace en masse...
Or perfectionists can just cope.
The PAIN of imperial units becomes unbearable when you do even primitive engineering. E.g. in SI force: N = kg*m/s^2, work: J = N*m, power: W=J/s. Check those out in imperial, all that zoo of variations and accompanying conversion constants. As a bonus, say, estimate the force exerted by a water stream of 1lb/s at 1ft/s. Does divisibility by 12 or 16 makes it easier?
Bringing back UA-cam video responses
I think you have missed that the UK system this is all based on has more units between a lot of these and they were used. Furlong and chain, for example. And stones in weight. We laugh at the US using pounds, we use stones and you ridiculously high numbers are massively reduced in the UK.
This chart is missing so many of the most used measurements in the US: blocks, football fields, over yonder’s, down-a-ways, go-thata-ways, hop-skip-and-a-jumps, ain’t-too-fars, outa-my-ways, and many others.
Around the corner and just over the hill

I think an interesting quirk about Americans and the imperial system is how we don’t actually use miles to measure distance all that often, we use time! This is because the average highway speed limit in the US is generally around 60 miles per hour, or a mile a minute, making conversion really easy. So while the distance between NYC and Chicago is 790 miles, it’s more practical to say it’s a 12.5 hour drive
I never noticed that before, but you're definitely right, at least in comparison to how I personally conceptualize distance. It certainly seems as though most people are more comfortable referring to a trip as "two hours away", rather than "120 miles". I suppose looking at distance relative to time does somewhat bring it back into "human useable" terms. I have no idea what two hundred miles looks like but if I said it takes about 3.5 hours to drive, I would have a somewhat more grounded concept of the distance.
I wonder if this mentality is a vestige of when people used to refer to places as "three days" or "a fortnight" away.
That really isn't a measure of distance unless you're talking about two points on a highway though. People use time just as often to talk about time between places within a single city, except the average speed there is definitely not 60 mph.
In my experience Americans are actually much more likely to describe the distance between two places in miles compared to Brits. And that's actually completely independent of highway speeds. I would say something like "Well it's not very far but it's country roads, so takes about an hour". I have *no idea* of the miles, only the time.
(Oddly this only applies to driving. I know the distance when I'm walking, but if you're moving under your own power you 'feel' the miles in a completely different way)
I hate this
never thought of it but its actually pretty efficient
The weirder and more obscure the units sound, e.g. furlong and hand, the more likely it is that they're used by people involved in some way with horses
exactly my experience as well, the first time I heard about hands, it was from an equestrian.
And isn't it funny... that a foot is not obscure, but a hand is. Of course, d*cks are out of consideration because sizes vary a lot :D
Furlongs were used to measure sections of fields for farming and most of the world actually has an analogous unit of length in their traditional systems. Literally "furrow length".

To be fair, barleycorns are actually still used in the present-day US.
They're hidden behind "shoe size," but the difference between any two consecutive shoe sizes is a barleycorn: 1/3 of an inch.
no fuckin way
In Europe, shoe sizes are a mess (probably also in other parts of the world, but idk): every shoe brand has the shoe sizes slightly skewed towards either bigger or smaller, meaning that you cannot use the size to accurately determine whether your toe will hit the end of the shoe or not. Sometimes the shoe size is also given in centimeters, but even that cannot be compared between brands because everyone seems to use the same conversion table instead of actually measuring anything.
It's like the size of the shoe has been measured in cm, that number was passed to someone else who in their head converted it to inches, passed to someone else who converted it in their head to cm, passed to someone else who in their head converted it to inches, passed to someone else who converted it in their head to cm, passed to someone else who in their head converted it to inches, passed to someone else who converted it in their head to cm,
only to be converted to the shoe size from the number that was left over after all those approximations during conversion.
@@hetsmiecht1029 In Japan we use exclusively cm for shoe sizes. You would think that would mean you could just measure your foot or one of your existing shoes and then order the same size, but somehow it manages to still be a huge ordeal to find shoes that fit properly. It never ceases to amaze how two different brands can make two shoes that are supposedly 27cm but one is way too big and the other is way too small.
Shoe sizes are objectively the worst measurement systems the world around. Some claim to increment based on fixed lengths (barleycorn, cm, in, or whatever you want to choose) that never seem consistent. Most are more like Celsius and Fahrenheit than Kelvin (why is a woman’s size *always* 1.5 sizes larger than a men’s??? Why is size 0 not a non-existent shoe??). Men’s, women’s, and children’s sizes rarely match up, even in the same systems. None of that even gets into width! We need some shoe (and in general clothing) size standardizations the world over way more than the US needs to completely drop customary.
@@ClementinesmWTF I mean, most of the world already uses cm for shoe sizes. But as Mari and Het Smiecht both mention, just because we size in cm doesn’t mean that this actually aligns to real-world consistency, because everyone defines how to measure the same dimensions differently.
I’m an American who moved to Canada, and it is infuriating. Imperial for measuring short distances and heights, metric for long distance. Celsius for the weather, Fahrenheit for cooking (the exact OPPOSITE of what it should be!) At least in the US we just have one system for the most part!
seriously! celsius feels like it's practically designed for cooking but is more annoying for ambient temperatures. also they tried to migrate to imperial for short distances but really didn't do very well, the reason metric is used for long distances is because it was mandated to be used in cars and on road signs and stuff
I find the metric system to be superior in every way except fahrenheit/celsius. Most people use temperature for food or for inside/outside temperature and especially for the latter Celsius just is too coarse. Sure it's nice knowing that sub 0 is freezing, but if that's really the only problem I can live with switching. Centigrade and Fahrenheit are just as arbitrary as each other. We could easily replace Kelvin with Rankine in the SI too (not that we should replace anything in the SI)
Canada's measurement system is totally ruined by its physical proximity to the US.
Why is weather measured in Celsius? Because the weather stations on local TV can freely use metric if they want, and so they do.
Why is cooking measured in Fahrenheit? Because historically there wasn't a good financial reason for manufacturers to sell a different kind of oven for the Canadian market, so Canada got all the ovens with Fahrenheit.
@@Unknownlight I just came here to say that!
@@unarei Nah. Very straightforward, once you start thinking in increments of 5 rather than 10.
Creator of “the chart” here; I never intended it to illustrate how ridiculous a system the English (length) units are, because I agree with your point: there is no actual system at all!
When I made the graph, I did so to get a better overview of historic and accidental relationships myself. The 6000 ≠ 6080 paths are in there deliberately, for instance, because those are two alternate definitions that have been used. The sibling weight chart has more of such cases.
By the way, did you publish your NIST chart to Wikicommons as well? It’s a nice and welcome addition.
Thanks for making it! It's really helping me out. Looking at it gives me a way more intuitive understanding of measures that I'm not familiar with, rather than having to pull out a calculator every time.
Yo.
Cool.:)
good idea! I've uploaded my chart there now. [ commons.wikimedia.org/wiki/File:NIST_definitions_of_American_units_of_length.png ] I hope it can be of use to someone down the line!

For those who have always wondered whose massive feet we based the "foot" off of, try measuring a hefty work boot, which is more like what most people would have worn on a daily basis at the time. Nobody is barefoot when they want to measure something out.
Is there an equivalent Hefty Work Sandals? the hollands didn't leave us any :(
Yeah but Henry I normed it
So you're calculating with the King of England's boot.
My shoes are conveniently very close to one foot long. If yours are not, you just have to calibrate it. It is probably more useful to calibrate your pace, however.
It is very handy to get a rough approximation of how big something is at work by just carefully walking, or by using my thumbs. If I ever need to quickly make sure I'm not too off a measure, and I left my tape measure somewhere and I can't bother to pick it up, boom foot n thumb time
My feet are roughly 1'1⅜. So that's about 111.5% more.
Roughly, good enough for small measurements! But if I used my feet to measure longer things in US feet, I'd have to add a whole foot every 7.5ish of mine, or more precisely, 32 feet to each 277 of mine. ... _if_ I did the maths right, of course.
You might define a unit of weight as being equal to 7000 grains of barely because it was the volume of a commonly used shipping crate. Then it might turn out that it makes sense to reckon the volume of ships' holds in terms of the this customary unit, the amount of barley it can hold.
Usually there are reasons for things. Usually those reasons made more sense at the time.
barley?
Yup. Exactly.
Just like how we often today denote container ship sizes in "how many containers can it hold", TEU (twenty-foot equivalent unit)
@@MarcusMedomRyding In like 200 years there's gonna be one of those charts like "omg did you guys know there's a unit called a container that's equal to 20 feet? Isn't that wacky!" The context of 20 foot containers being a good size to fit with all of our shipping, rail and trucking infrastructure might be lost as technology evolves. Metric units were designed artificially with the priority on a rationalist aesthetic and are obviously better for science as a result, meanwhile imperial units were designed for a specific use-case over a long period of time and generally prioritize function over clean conversions, they're not really comparable systems because they had different goals from the start.
In defense of water over barley, it is a resource that is necessary for human survival and therefore found/used in every human society. Whereas barley does not have this same advantage. Not gonna comment on why a liter of water tho
Just a note, a nautical mile has nothing to do with a typical mile. A nautical mile is the median arc length corresponding to one minute of latitude. Or 1/60th of a degree of latitude
I never knew that, always thought it was just a strange subset. TIL.
And a knot would be a nautical mile ("knot"-ical mile) per hour, or in other words an arcminute of latitude per hour.
@@rauhamanilainen6271 it used to be the distance between knots in a standard rope divided by the time it took the rope to get out of the ship when it was stuck by an ancor, I think
This highlights the point even further that imperial units were better at being subdivided, when there's a system of measurement that can be divided by 1, 2 ,3, 4, 5, 6, 8, 9, and 10, not once, but twice (poor 7 lol)
@@dinamosflams Not quite. First off, in the good ol' days of sailing, they used to use a chip log (a flat board that would catch the water and would thus be stationary in the water) to measure speed. As the boat was moving, they would throw this over board, and then they would let the rope slip out and they would count knots set in the rope. The unit of "knot" does get its name from these knots, but the knots were set at precisely the distance required so they would translate directly into nautical miles per hour.
Barleycorns *are* still used, we just don't call them barleycorns any more. They're used to measure shoe sizes.
Lmao is this real
@meee_5155 every 2 shoe sizes the diffetence is 1 barleycorn (1/3 inch)

You know why the French adopted the metric system? (They didn't invent all of it)
It's because they had over 400 sets of definitions of weights and measures. There was Parisian pound and lyonnaise pound, this foot and that foot and yet another 399 feet definitions. Each town had one. Same of course for ounces, inches and so on.
So instead of trying to unify all that, they cut the Gordian knot and got rid of all of it.
I think the British did just something similar their imperial system when they got rid of their Winchester system
@@jmurray1110 you again? Lol
As a french person I agree
And plus the entire world adopted these measurements because it was way more practical than converting between different units in each country. And that's the main advantage of the metric system, that it's universal and makes people not use conversions. Not just that it's more logical. That's what Americans don't understand, it was impractical to convert between a thousands different units so everyone switched to the universal standard. Everyone except them which still hold on to their outdated legacy units.
Wait what they did invent it
And they were the first to fully adopt it

My favorite quote about metric and imperial system goes like this:
“In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade-which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘Go fuck yourself,’ because you can’t directly relate any of those quantities.”

also the whole teaspoon->tablespoon->cup->pint->quart->gallon progression is essentially a microcosm of this, since with the exception of like quarts and gallons all those units are largely independent in usage. If something is measured in cups, you just say "two cups" instead of switching to pints. If something is measured in tablespoons, you would just say "four tablespoons" rather than a quarter-cup. It's a system which is good for cooking (what most people most commonly use volume measurements for), since it's easy to get an intuition for how much each individual unit is, and follow/adjust recipes based on that. Plus, a volume system based on powers of 2 is more easy for a person to approximate without measuring than one based on powers of 10, and a system based on pre-set values which you already have vessels for is quicker to use precisely than one which you measure with a scale. Not a super high *degree* of precision, but you don't need that in cooking.
It does immediately fall apart if you try to use it in any other context, though.
i gonna have to dissagree on the independent thing. I work at a kitchen and we often are sharing our measuring cups and buckets, so it becomes really difficult when the recipe ask for 1 1/2 gallons of water and the only thing you have are in quarts.
You need precision for baking though, which is the branch of cooking that relies the most in measuring stuff. Besides, the fact that a tablespoon of brown sugar has a different weight than a tablespoon of white sugar is the most inconvenient thing ever. Maybe in 1840 it was useful, but modern people have digital scales. Having those different spoons to measure is proof that you need special tools to make imperial have any sense. It could be just as easy to have those spoons in metric: 5ml, 15 ml, and so on. But we normally don't have those because it's not necessary in my opinon.
@@jmiquelmb I'm genuinely curious, when has the weight of a tablespoon of brown sugar vs white sugar been a problem for you? I haven't come across a recipe that has that problem.
@@aliceiscalling When you want to change white sugar for brown sugar, or the opposite, since you want to keep weight, and tablespoons are a measure of volume. Same for castor sugar vs granulated sugar, and many other ingredients. Using volume to measure solids is incredibly cumbersome.

For people who want to know why there are 5280 feet or 1760 yards in a mile, it is because of a compromise, and standardization from around 13th century England. Official unit systems historically were always a _legal_ standardization of what people were using and came up with themselves (evolutionary developed, not designed) that they found useful. So when the first English standardization happened, they had to settle on the definition of the English foot, which they defined in relation to the (legacy) Saxon foot. The English foot was defined to be 10/11 of the Saxon foot. But this then meant that the new hypothetical English mile would be 10/11 of the old amount, and the cost of changing all the road signs (yes, even back then) would be too much. The original Saxon mile was defined as 1600 Saxon yards or 4800 Saxon feet (why this was chosen requires a little more of a history lesson). So instead of changing all the road signs and maps etc, they just changed the definition of the mile to be 11/10 (10%) larger, and that's where the 1760 (1600 + 160) yards and 5280 (4800 + 480) feet comes from for the definition of a mile.
Oh, I thought the 1760 number just came about from units in between feet, yards and miles that had smaller numbers (eg IDK… 28) that were forgotten - eg furlongs?
You telling me that the metric system is the single most successful conlang ever conceived?
@@iamthinking2252_ : When the English mile was standardized, it was set to be a whole number (8) of furlongs (660 feet), because the furlong was a well-established unit, and nobody wanted to screw up all the existing property records that measured land in furlongs.
A furlong is "a furrow long", i.e., the length of a trench made by a plow in a farm field. Because there's only so much distance a farmer could plow before he had to rest his oxen. The furlong was ultimately standardized at 10 chains, or 40 rods.
A "rod" is 16.5 feet. This makes no sense with the modern foot, but in old Saxon units it was a nice round 15 feet.
Interesting.
Thank you.
@@danielbishop1863 you've got it backwards. A furlong was 600 saxon feet, therefore it would become 600+60 English feet. And then a furlong was still 1/8 of a mile.
In catalan, we have an unofficial unit of measurement called a "hand" ("pam"), which was used quite often at least by our grandparents' generation.
A hand is commonly defined as 20cm, but the truth is that people just measured things with THEIR hands and got a number out of them. So if your grandma says that the table is "7 hands long", you actually have to take into account the size of her hand. What she's actually saying is "this table is 7 grandma hands long".
Essentially everyone had their own unique unit of measurement, in a very toki pona-like manner. Of course we use metric when any semblance of precision is required, but it isn't uncommon to say things like "he's two hands taller than me".
There were also a lot of people who knew the exact conversion between their hand length and metric, and could get scarily accurate measurements of things just by sizing them up with their hands.
For day-to-day measurement, this sort of thing just isn't an issue.
"Three by three feet of cloth" is pretty straightforward to visually understand, especially when you can SEE that the other guy's feet are smaller than yours and they're counting by THEIR feet, not yours.
You can (theoretically) do precision engineering and architecture with "arbitrary" measurements like this, as long as everyone on the team can check each-other's work. Big-Feet Tim can SEE he's got big feet, and ask Normal-Feet Nathan to help him measure. If you're working alone then you don't even need that.
As distances get bigger, that's when these systems of measurement break down. If you're sending goods or information a week down-river, how will those recipients know how big YOUR feet are? Do you send one of your shoes with the package?
Extend the differences further and things become hopeless. Now you're far enough away that even broad generalisations like "apple-sized" or "horse-sized" might not apply, because this region has different horses and different apples. That's assuming everyone's working in good faith, and you won't want to do that after the first time you buy "ten stones weight" of goods and discover that bastard was measuring with pumice.
@@Ninjat126 because your feet are 12 inch long? (us size 12 and 13 for women) My guess is that you just don't care
[insert Robot Wars joke involving Panic Attack here]
Here in Colombia (At least in the Caribbean) it is common to do that also! Just that a bit different... We use fingers: We measure things sometimes by putting our hand horizontally and counting how many fingers (Except thumbs) fits on the object's length. Maybe we use another thing to measure, like our foot or anything that's useful to see.
Obviously, this is NOT used when precission is required. This is just a "handy" way to measure things, since it's a bit more visual than saying "about 6 cm".
By the way, don't know why I'm writing this in English since we both speak Spanish (Probably).

As a stormwater engineer, I find it necessary to point out that 1 ac-in/hr of rain is roughly equivalent to 1 ft^3/s. So if you know the watershed area in acres, and the average rainfall in inches/hour, both of which are common measurements for those things, you have found the flowrate in cubic feet per second and I think that's neat.
To be ultra-precise, an acre-inch is 3630 cubic feet. Since an hour is 3600 seconds, an acre-inch per hour is 1.008333... cubic feet per second.
@@danielbishop1863 the conversion is 1 within three sig figs so for most practical purposes yes he does know.
This works in Metric extremly well as well.
Rainfall is given in mm/m² which is l/m². If you just add a time unit ontop you have your flowrate.
This works great for scaling issues.
Got a few km² of rainfall, just multiply the km² Number and add a factor of 10^6 and you got your complete Liters. If you want m³ then you just add 3 zeros or a factor of 10^3.
That is what i like about the metric system. If just scales well.

Fun fact, while we don't have a 30 cm lenght unit, most of us who grew in metric countries can probably visualize that lenght without subdividing the meter because the rulers you use in school are exacly 30cm long, i'm guessing people who grew up in imperial countries had the full foot?
Also we do say 30cm, no one uses decimeters, or decameters or hectometers. Much like miles and feet we almost never convert opting instead to use decimal point to increase precision at first.
Here in Ireland metal rulers are usually metric (30cm) and wooden ones are almost always metric on one side and imperial on the other. Tape measures are sometimes metric and more commonly both.
in the US, our school rulers have both metric and empirical on em and are generally only a foot/~30cms long lol
well decimeters are used in sweden semi frequently...
Exactly what I was thinking, although I would say metric prefixes always refer to a multiple of 1000 (eg kilo, mega, giga, micro, nano ...) with the exception of centi. So we would say 900m not 0.9km and 8km not 8000m

The fathom, 6 feet, is based on the approximate average male arm span. This is useful when measuring the depth of water with a rope with a weight on the end, pulling it up hand over hand. I delight in this.

Simply unfathomable
Fun fact:
Having a separate unit for temperature is itself completely arbitrary. If you fix the Boltzmann constant as 1, you get temperature in terms of Joules. Some statistical physics books actually do this.
Doesn't the zeroth law of thermodynamics rely on/define temperature as an intrinsic parameter though? (or whatever it's called, my thermodynamics isn't very good)
But units are good! You don't want to measure temperatures in Joules, or distance in seconds (if you set the speed of light as 1), because then you lose the ability to check that your computation gets you something with the right units.
That is, unless you're some weird theoretical physicist.

A note on cables and fathoms:
These are units designed to measure rope for fitting out a sailing ship and for sailing the ship with a crew who mostly have little-to-no formal education outside of practical matters related to their profession.
A fathom originated as the distance between your hands when outstreched. If you've ever coiled rope you'll know that stretching your arms out and then brighing them back in while holding the rope is a very neat and efficient way of making a coil or taking a measure of said rope. Given the average dimensions of a human, this figure comes out to around 6 feet, but historically standards varied by as much as a foot in either direction. Depending on where and when you are this may have been as short as 5.5 feet or as much as 7 feet, but given time and practice (both in abundance at sea) your common sailor would be able to work out about how much slack to give or take to come close enough to the standard at the time for most purposes, and anything that requires precision such as water depth or speed would be measured with a pre-marked line.
A cable length is originates as literally the length of the ship's anchor cable. Again exactly how many fathoms of cable you would need for this and how long a fathom is varied with time and place, which is why this unit doesn't fit well into most versions of "the chart". If you were to ask the United States Navy, they will tell you that a cable is 120 fathoms. In the Royal Navy a cable is 101 fathoms. In practice, this discrepancy doesn't really matter.
In short, like the rest of the "imperial system" these units have a specific application, work intuitively within that application and were never intended to be used for much else.
Wow, this seems....
"unfathomable."
I use fathoms in every day life, and I am not a sailor. No special reason, fathoms are a good unit.
So these units are basically "whatever, we'll fix it in post". Makes sense.
@@Illliumthey didn’t really need fixing because they were historically used in applications where ballpark accuracy worked fine. If a ship is coming at you, saying it’s “2 cables away” when it’s actually only 180 fathoms away doesn’t make much of a difference.

Remember the good old days when there were 12 pennies in a shilling, except in Jersey where there were 13 and the Isle of Man where there were 14, 20 shillings in a pound and 21 shillings in a guinea? The penny was divided into four farthings and the farthing was divided further into halves, or thirds in some colonies and quarters in others. Common coins were the farthing, the halfpenny, the penny, threepence, fourpence, sixpence, shilling, two shillings and two shillings and sixpence or half crown. I should have mentioned that five shillings were a crown, but crown coins were often only issued in coronation and jubilee years. We should go back to the old system after Brexit.

Ah yes the old days where conversions were a nightmeare
As an American, I was a bit envious of the superior British monetary system, at least until they needlessly desecrated it on the altar of decimalization. Still, sad to see it go, always sad to see something quirky and human be destroyed in the name of homogeneity and soulless standardization.
I find it funny that so many people who make fun of the Americans for their out of place systems when most of the "Americanisms" were shared by the two until the 1970s and 80s. I guess it's because you don't really need to LEARN English living in the UK, it's the native language. Even silly things like calling football soccer (a distinction because we have our own football of course) when Soccer is still used in Canada and older football fans in Britain.
I'm certainly glad we never had to deal with currency conversion for everyday transactions, though. I remember seeing the Pilot episode for Doctor Who where they talk about how in the future, the pound is put in terms of Decimals, which in real life, would have only been in 15 years but was unthinkable in 1963.
The guinea is hilarious to me. A unit of currency worth 5% more than a pound.
I find it helpful to consider the historical roots of different units. For example, the acre. An acre is an amount of land which one person with one ox can plough in one day. Not only that, but an acre was generally defined to have a particular shape, long and narrow, which is most practical to plough (because turning a plough around is inefficient).
even though it’s not particularly convenient from a standardization perspective, i find it very useful to have multiple systems of units to connote different uses. an acre is very useful for measuring agricultural land, because it was designed as a measure based on agriculture labor. Likewise a mile was designed to measure long distances travelled on foot, while a block has absolutely no standard definition but is universally useful for describing distances in urban environments. I love having multiple units of measurement.
To my knowledge, a block is about 1 cubic meter and works quite well when playing Minecraft.

One thing I wish you had touched on was units of pressure, which are surprisingly bad in metric. A pascal is defined as a Newton per meter squared, which is a comically unwieldy unit to work with. A bar is defined as 10^5 pascals (breaking the otherwise consistent power-of-ten prefix system) and manages to be just slightly short of 1 atm. Atmospheric pressure is 1.0135 bar / 101350 Pa, which is sometimes enough to be a problem in calculations (but not always!). On the other hand, a psi (pound of force per square inch) is a much less unwieldy unit, and while atmospheric pressure is 15.7 psi I think it’s at least useful in that it’s never ambiguous whether or not you can be lazy and pretend 1 bar = 1 atm. Altogether I think this is a rare place where the metric system is at its limit and is arguable strictly less sensical than the imperial system
Edit: 14.7 not 15.7 psi
Also: people don’t use centibars, kilobars or megabars, they use kilopascals, megapascals, and gigapascals, which are tough because they’re defining things in terms of the awkward tiny unit instead of the not-quite-atmosphere-pressure unit and it’s impressively difficult to get a sense of how much pressure that actually is; I couldn’t give you any physical intuition as to what might exert a megapascal of pressure on an object. I’m a chemical engineering student so if there was anyone who should have that intuition it should be me. I can only (unhelpfully after a bit of mental math) say 1 megapascal is sort of like 10 atmospheres
That's why metric has sensible methods of scaling unit. The bar isn't exactly a hectopascal, but close enough. The bar is a non-metric measure, and the hectopascal and kilopascal (if you're Canadian) are the usual measure. The Pascal is closer in purpose to the psi.
Quick question: how many bar per psi?
Consistency and accuracy are more important than what you consider unwieldy.
@@talideon a hectopascal is .001 bar. If they are the same I am going to put you in a room at 1 bar then cut a small hole in it, exposing it to an environment at 1 hectopascal.
A bar is 14.5 psi.
@@martinsriber7760 I work with these units for a living, trust me when I say that it is preferable if your engineers have a physical intuition for what a unit is. Makes problem solving a Lot easier. Psi are stupid in other ways because of pounds force vs pounds mass but there is not a perfect unit for measuring pressure
In a surveying class I took for my Civil Engineering degree we had to learn all sorts of obsolete units of distance measurements "just in case". I never did any surveying outside of that class but from what I learned surveyors need to know these units because they might come across a measurement that was recorded in older units.
Depending of the state surveying in the US has metric, international inch(1961) or customary inch (18xx)
seems like the sort of thing you'd only need to know *about* so you can grab a handy table when you run into it.
one thing that i think is important to understand about the imperial measurement system ( as it exists in the US ) is that a lot of these convoluted and meaningless relationships were inexpicably things you were meant to learn in school ( in particular the mile/foot thing ) - which ends up making them reviled by young adults
not reviled enough apparently
It's especially bad in Canada where you're often forced to learn the conversions between Imperial and Metric on top of that.
the problem is there are people who actually defend the imperial system and
this guy singlehandedlg bogged down efforfs to replace the imperial system as a "joke". As someone who has majored in sociology and the studies of political activism online, and having been features on the news many times, people do not believe me that when they make controversial
videos as a "joke", they are actually ignorant to the fact that the idea isnt as controversial as the idea theyre attacking
that's what happens when you value "rigor" over usefulness
They taught me standard better than they taught me metric, and at a younger age too. USA be wack.
For any of you folks out there who've never used Imperial measurements and imagine they're like the worst thing ever, a good illustration for what Imperial measurement is like would be how pretty much everyone measures time.
Time is measured using a number of arbitrary units, and there are conversion factors including but not limited to 7, 24, 30, 52, 60, and 365.24. Now all of this isn't exactly ideal: If you ever need to convert 1.573 days to seconds, you're gonna want a calculator. However, that was an arbitrary, contrived math problem and you just don't need to do those unit conversions very often in everyday life. If you need to precisely convert units en masse, there are computer programs to do so, and in other cases mental math usually suffices.
Time is indeed measured with weird ass numbers, but if I could choose a system of measuring time that would use base 10, I would. Wouldn’t you? Fact is, time is a mess because we don’t get to choose when it’s day or night, but we do get to choose what a pound or killogramme is.
@@cluelessmango768 Day, month, and year are units that are helpful to have, yes. But if we wanted factors of 10, there's nothing stopping us from replacing hours, minutes, and seconds with centidays, millidays, microdays, etc.

Why this happens definitely has to do with the factors of 2.54^2, but I'm not really sure which ones and how exactly. An infinite geometric series, maybe?
Math graduated student here.
It's most likely because a power of 10 is very near to a multiple of 254*254 = 64516 = (2*127)^2.
Powers of 10 from 100 onwards have gcd 4 with 64516 so that is the minimal distance between their multiples but that could be achieved only by multiples of powers of 10 with coefficient different from 1 (does it?).

I'd like to add that I really appreciate how the Imperial system of lengths works for sewing, as someone who does a lot of that. Yes, the metric system is easier to multiply by 10, but you are not multiplying by 10 when sewing. You are dividing, specifically by two more than once, which gets Real ugly with 10, but is very nice with 36 and 12 and fractions of an inch! I like being able to divide inches when doing seams instead of having to work in arbitrary numbers of millimeters (too precise), or numbers of centimeters (not precise enough). like you got 1" 5/8" 1/2" 3/8" 1/4" 1/8". very directly related to each other. all the precision you need. easy to remember. Also easy to standardize for different "types" of things you're sewing: clothes are 5/8" or 1/2" seam, accessories like purses are 1/2" or 3/8", quilts are 1/4", and French seams are 1/8". You can remember that and use it when you don't have a pattern to work directly off of.
Yards and fractional yards are also really convenient to work off of when buying fabric: inches turn into fractional yards really really nicely. You can take a 5'4'' measurement for a cloak, which is 64'' just by remembering the multiples of 12 (remember your times tables? i learned those in 3rd grade), which is 1 and 2/3 yards! Very easy to remember and go to the fabric store and buy the right amount of fabric (though i would round it up to 1 3/4 yards just to be safe).
I dunno. I think that being able to use a system that's really well optimized for some things is better than having to use something that's optimized for something else just to appease some nonexistent god of Consistency and Objectivity. Sure, the metric system is absolutely better for scientific measurements, but it is foolish to say that we are purely scientific beings. We are humans who have feet and digits and for the vast majority of our existence had no decimal system, no calculators, no easily accessible paper and pencil, and no idea what "universal constants" were, and the Imperial system shows that. In addition to all the completely valid reasons not to like the Imperial system, perhaps that is one reason people don't like it. But then again, who knows- I'm just a random person in the comments section of a UA-cam video.
By your logic, Imperial is actually worse, since you can only halve, yet in metric you can also divide by five. Of course, this can be avoided by simply choosing highly composite starting lengths
@@Anonymous-df8it I'll clarify my point- my opinion as someone who sews is that the Imperial system is better than Metric for sewing, because it makes clean math with the divisions and multiplications and additions and subtractions you commonly need to do while sewing. I don't think I've ever needed to divide by 5 in any of my projects, because it doesn't make sense for doing anything with fabric. On the flip side, there are other things that Metric is much more useful for than Imperial: for example, I've worked with my dad in his metal workshop, and I have seen how being able to represent very high degrees of precision with decimals is useful for working with metal. It all depends on what you're doing, which is a sentiment I've seen many times, just often with the inaccurate implication that Metric is for when you're being a Smart Scientist and Imperial is for when you're not doing anything that requires math. I guess my original point was, no, actually, sometimes math with Imperial does work out better, it just depends on the kind of calculations you need to do.
@@river446 Out of genuine curiosity, do you ever really need to work with units smaller than ⅛ of an inch? That's about 3 mm, so using that and multiples of it when working with sewing in metric doesn't sound like it would be that bad. I should ask my grandmother how she does things, she does quite a bit of sewing.
On a related note, before now I had never really understood why unicode has fractions up to ⅛ but not really any others. It seemed so very arbitrary. I hadn't ever really given it any thought either, and not connected the dots when hearing about x/8th inches in some videos before. Thanks for (inadvertendly) pointing that out!
When I worked seasonally in construction in Canada, usually measurements would be to within 1/8 of an inch, but sometimes 1/16ths would be used, which I think could be eyeballed fairly well. As I remember, 1/8 was roughly the width of a saw blade, and also about the (shorter) width of the lead in a carpenter's pencil. The wood of a carpenter's pencil is 1/2 by 1/4 inch, which is convenient for spacing things.
2:36 fun fact, actually!
We do sort of still use the unit "pica." I work in a historic print shop and it is very commonly used there, to the point of having special pica rulers. Many typographical things are measures in picas and points (as mentioned at 3:54). A pica is almost exactly 1/6 of an inch, and a point is 1/12 of a pica. For example, a 12-point font is exactly one pica tall. Therefore, if you are typing and the font size is divisible by 12, your text is that many picas tall. I believe that historically, picas are a bit off from 1/6 of an inch exactly, but the picas and points used in modern text editing programs do correspond to exactly six picas per inch.

I was quite surprised by how much those units influence our way of thinking. For example Americans using different systems for “length” and “distance” sounds so strange when it’s just a larger number for us.
I guess imperial trains us try and keep things in a range of 1/4 unit to 10 units although being in the hundreds is fine.
And since im an engineer I'm used to metric as well and often estimate stuff under an inch with cm or mm to try and stay within that 1/4 to 10 unit range.
Although the video makes the point that measuring human scale objects like furniture doesn't need to be easily convertable to the unit for long distances. A couch can be measured as 10ft long and a city is 10miles away, although we measure trips as both litteral distance in miles and travel time in hours or minutes as relevant.
I see it as metric as great for science with its easy conversions, and imperial is great for human scale without breaking out decimals or weird fractions.(although both have some hidden abominations like the metric ton being a megagram or the fact a pound mol exists for imperial the way mol exists for grams in SI/metric)

As an engineer I have a mixed relationship with whether the US should switch or not. Switching would make it consistent with the rest of the world and make measuring things a lot nicer (for instance, I'm taking thermodynamics and 1 Pascal is defined as 1N/m^2, which is very helpful for keeping track of units). However, the process of switching would be pretty painful for those already attuned to using imperial. It would take me a while to understand how far a km is or how hot a degree celsius is in day-to-day life.
Basically, I wish we would have switched to metric when the rest of the world did.
you know that metric is not that old, and at one point in the 20th century, the whole world passed to this process of switching, right? like, THE WHOLE WORLD MADE THIS EFFORT TO HAVE JUST ONE SYSTEM OF MEASUREMENT IN THE ENTIRE WORLD, and just americans were like "yeah, but no".

I don't want to know because my country made the effort to switch at one point in time. people complained people weren't used to the new way, and things get confusing, but in a short time everyone knew how to use metrics and we just forgot about the other methods.
but them we buy something from the USA and nothing makes sense anymore.
@Edson Vinícius Santos Vaz Ronque so if you're getting products from the US with Oz on it, it also has the metric equivalent posted on the product. Everything in my kitchen with an imperial unit on it has the metric listed as well. So there is no way you're confused by a product you got from the US. Also not knowing how big a 55" TV is is pretty unimportant.
It would also be incredibly EXPENSIVE. Just imagine how many hundreds of thousands of road signs would need to be changed or reprogrammed in metric. Speedometers in the US read primarily in MPH (analogue dials sometimes have smaller KmH denotation, but often digital gauges only read MPH, cars might require software upgrades). Food packaging would have to change where it's not already in liters or grams (yes Americans use those in grocery stores sometimes-in fact our nutritional labels are in metric).
That's ignoring public resistance to changing the way they go about their daily lives!
Now that you explained that miles and feet come from two different systems of measurement, everything makes more sense. Obviously when converting between systems there are going to be wacky numbers.
"units having silly names is a good thing"
As a fan of the barn-megaparsec, I concur
What's a barn-megaparsec?
One interesting thing about 5280, the number of feet in a mile. It is divisible by 2,3,4,5,6,8 and 10. That may have something to do with why it's used.
This is a great point I hadn't thought about.
Yep, and it makes sense actually, I really only have American perspective on this... but we seem to use ½ miles and ¼ miles and so on more often, while other countries would say 0.5 km and 0.25 km because their system is made for decimal. Same with cups and pounds, vs liters and grams. We like using fractions
@@caritahearts2405 just for context, we don't use "0.5km" or 0.25km" we use 500 meters and 250 meters, when we have to work with decimals we automatically convert the unit, because it is very easy to do
@@caritahearts2405 The metric system is not made for decimals. Who in the right mind would say 0.5 Km or point 0.25Km? It would be better if you said that it was made for whole numbers. we can convert everything into an actual real value because its an ACTUAL system. Hek, we say half a kilometer or a quarter kilometer more than actually ever using decimals. Ironically, Imperials use decimal a hek of a lot more often than Metric because it cant do anything that doesn't have an exact value and thats what most people hate about it.
Great point lol. I convert my videos to include metric stuff because international units are pretty useful to have in your pocket. I'ma take the time to learn the metric system so I don't have to say "I'm 5'6" when discussing my height.
I appreciate your comment on feet being a "comfortable" unit for working on human sized things. As a metric Australian (born in the 90s even), I do find inches far easier to visualise and think about than centimetres. Centimetres are too small for anything I'm directly going to use, and being a little bit off in my guess of a centimetre is proportionally quite significant. Estimating inches feels much more reasonable.
As someone brought up in an exclusively metric environment, I also have issues eyeballing stuff... Don't know if it's because of the metric system or because this skill isn't taught.
@@_blank-_skill issue, no joking tho.
My professor can say kinda accurated how many cm some stuff is just seeing it. He's mechanical engineer.
I'm trying to get that ability as well. 😅
There are a couple reasons why, and its because what they are based on. Each segment on your fingers is about an inch and your foot is about a foot, also because the inner side of your forearm is the length of your foot you could also say that the inner portion of your forearm is about a foot. You look at these things for 16 hour a day, every day, and see these things on other people at varying distances, which means it more intuitive at guestimating even when farther away. Not to say that a meter can't be taught to be recognized in real space, just that humans without outside intervention will relate to the things they can touch and feel.
Metric is better for exacts and abstracts. Abstracts in that you really don't visualize what a kilometer or mile is, you visualize how much time it takes based on how fast you are going to go what you are told is that distance. Its a scale that is too big for people to think about that way. And exacts as in... you know.. you need to follow something exactly.
Which is total self-deluding, strawgrasping bollocks. All that makes you look like is that you're afraid of numbers larger than one. Guess what, there is no inherent comfort in 1 inch over 3 cm just because one is 1 and one is not. Nobody said your feeling had to start with the first integer multiple of a unit. Comfortable is what you GOT comfortable WITH, including what number and unit you got comfortable expressing that with. This "comfort" argument is entirely and by necessity self-defeating.
You can just estimate in multiples of two. Like, I can estimate in centimeters up to like 26cm and then I switch to x2: 28, 30, 32, 34... In the same way I can only estimate millimeters up to 15, then I stop and go in multiples of 5
“The Chart” states hands are not in general use, but they are a common way to give the height of a horse.

@@yozul1, honestly, I was under the impression the unit was used to give a sense of scale in horse races.

I like that the units in imperial have many factors. 12 inches in a foot, so a foot has 3 factors. I took woodshop in high school, and preferred using the imperial system in there because it was easier to measure halves, quarters, eighths, and so on. The metric system is easier IMO for math/science calculations.
The true issue is that we do not use a base 12 number system. Base 10 is frankly weird and not ideal for dividing in metric. Imperial kinda accounts for this in a decent number of practical applications, but if we were base 12 the metric system would not have the issue to begin with.
That's basically what most Americans do anyway; Imperial to eyeball it, metric for precision. It's easier to visualize a foot (your foot) or an inch (first thumb segment) than it is to visualize a meter. "six feet tall" sounds more impressive than "1.8 meters tall".
@@MachineMan-mj4gj that's only because you grew up with imperial, not an inherent quality of the units. I can't visualise feet well in the slightest for example and always have to roughly convert to metres for it to make much sense to me at all

@@MachineMan-mj4gj yeah... it is, that's my point. Because I only really grew up with metric, metric is what's intuitive to me. Neither system is ingerently more intuitive than the other

I'm an engineer in America, and one of the great pains in my life is dealing with converting between energy and power units in my job. In college we're taught both metric and imperial together, and in that context, it becomes excruciatingly clear how awful and mish-mashed the imperial "system" truly is. I agree it's not quite as bad as some of its detractors who've never used it say, but in a technical environment, it is just awful.
One of the worst things is that we measure all our electricity in Watts, but we measure thermal power for things like heat pumps, air conditioning, and water heaters in BTUs (technically, the analog would be BTU/h, but I'll just use BTU for short). Problem is, all these BTU-based thermal devices are often _powered_ by electricity, _and_ we have natural gas power plants (and the energy density of NG is measured in BTUs) _generating_ Watt-based electricity, so we are converting between the two units constantly. BTUs are the most arcane bullshit unit ever conjured, and they're not consistent from medium to medium or even temperature to temperature. It's like if you took a Calorie and put two big question marks at the end of it.
The whole thing is a mess and it's about time they just scrapped everything and converted to SI. I sooooo miss dealing with shit like Joules, where the conversion to Watts is literally just to divide by time in seconds. Why can't we have nice things?!
Because people have a tendency to misplace decimal points. The calculation still looks good, but it is off by orders of magnitude.
Even though I’m American, I surprisingly was taught about centimeters back in kindergarten class. But that is all they taught us, I used centimeters so much I always thought they were a weird division of inches, I was shocked to learn centimeters are an entire different system.
Edit: Yeah so apparently what I find surprising is surprising in of itself.
America technically is on metric, because we define our imperial units by metric units, so it's not that odd imo.
What’s surprising is you think this is surprising. Most Americans are taught the entirety of the metric system alongside the US Customary. It’s weird that you were taught so little
When I was in elementary school, I think it was still thought that America would eventually go metric, so we only used metric units in Math.
Oddly enough, I've gone into a career in science, and we do use metric exclusively. (Yes I, and American, use the metric system. GASP!)
@@ClementinesmWTF That’s weird, I had to research the rest of the metric system on my own time.
@@jstnrgrs changing all the signs is a waste of money, and everything else that's objective has been changed.
as an American who uses imperial every day, I have literally never heard of the majority of the measurements on that chart lmao
same al ive heard were centimeters, milimeters. feet, yards and miles lol
As an Australian, we have used metric since my mother was in school. I'm acquainted with most of them to some degree though, hell even here despite being metric the registries usually require we still use hands to measure our horses.
Pounds and stones (14 pounds) were still semi common when I was a kid in the 80s to measure a person's weight. Mostly that's died thankfully.
Nautical miles, and knots, are stil referenced especially in maritime service and flight as well.
Pica and Point are used pretty much globally in printing still.
Acres are still used for area when we're talking land.
Grain is still a unit of weight used for propellant in firearms, also the weight of arrows and crossbow bolts.
So yes while they're antiquated and annoying AF when you're constantly having to do conversions, aka me, a lot of them still get used in edge cases I just went for ones I know are still commonly employed in at least a limited sphere.
That's not surprising. This is a complete system, it's just that most of the units don't serve a particular point these days that can't be served with one of the others. For the most part, the gaps are either only apparent for things like physics/engineering like slugs or fall in the hole between yards and miles. Chances are that you're not talking about things of that length often enough to care about having to use slightly larger numbers of either feet or yards. Chances are in that range quarters of a mile are good enough for the precision of what you're doing.
I've gotten pretty used to using metric since my firm has been metric-only since the 80's. But I grew up learning imperial first, so I constantly have to translate... Which is annoying. It's especially annoying when people use weight and mass units improperly.... I'm looking at you pound-mass and Kilogram-force.
Same
6:08 I think this is the whole crux of why users of either system have trouble understanding or adapting to the other one. Users of the imperial system avoid conversion, work around it or prefer to work by halving their measuments leading to fractions such as 1/16 or 1/32 while the metric system outright depends on the conversion for it to work. When a metric user has to get a quarter of a meter they commonly "convert", or more accurately change, the scale of their unit to centimeters to get 25cm instead of 0.25m. When the number starts to get inconvenient for daily use, metric users just dynamically switch the scale which is likely a foreign way of thinking for imperial users. On top of that, the concept of working by halving isn't really a common way to work in the metric system which might be awkward for people who are used to that method.
The two systems are almost polar opposites in their everyday use which makes grasping the other side's view hard. They utilise different methods. You can't use the metric system like you'd use the imperial one and vice versa. If you treat the suffixes of the metric system as their own independent units you're immediately doing it wrong just if you'd try to mix and match feet and miles in the imperial system. You can't just switch the units without also switching the way you use the units.
We work similarly to a certain degree. We say half liters and not 50cl. Or half a meter and not 50 cm. In fact if we wanted to be more accurate we would say 1 cubic decimeter and not 1 liter.
But yeah. You are right that we easily change scientific prefixes depending on the convenience. 20 cm instead of 0.2 meters. 2 kilometers instead of 2000 meters since we are taught that since primary school. Very good observation.
@@hodb3906 The funny thing is that in American schools we are now taught all kinds of history and reason the metric system is better, but we aren't actually taught nearly as much about the imperial system our lives are dependent on. Current curriculums are clearly biased to make the younger generations want the metric system instead of the imperial system. But it just makes our lives more difficult. Why do I need to know how a meter was defined, but not taught how a mile was defined? We might be taught that a mile is a Roman mile, maybe even that a Roman Mile was 1000 paces as mentioned in this video. But what is a pace? Is it arbitrary based on how long your legs are? Is it counted by each foot hitting the ground? No. A Roman Pace was a standardized measurement. Counted on the left foot hitting the ground, at infantry marching speed. Meaning that while in formation marching, every 1000 times your left foot hit the ground, you traveled 1 Roman mile with very little inconsistency. The entire system was based around the practicality of being able to measure without tools.
Also the term "milestone" comes from the fact that on Roman paved roads they placed a particular stone at 1 mile intervals. On each of these stones was a number indicating how far from Rome you were. This is also where we get the idiom "all roads lead to Rome" as all paved roads in fact did lead to Rome.
@@abonynge As far as I know all US customary units are based on SI (metrical) units (and have been for decades). So why should it matter how they were defined in the distant past?

@@harmless6813 The same reason the way the metric system was previously defined matters. It is no longer measured by things like the circumference of the Earth. But we are still taught that because it helps people understand the basis of the measurement system.
With metric it actually matters less than it does with imperial. With the imperial system most measurements are anthropic, meaning you can use your body parts to get a rough estimate. The inch is around the width of the average male thumb. In many languages the word for inch is still the same as the word for thumb. The foot was initially the measure of the average male's shoed foot. Materials to make shoes have improved so they are thinner than in the past, its roughly equivalent to a size 14 US sneaker. You are supposed to be able to get an estimate of feet by walking heel to toe in shoes. The list goes on, but knowing these things does find use in every day life for many people.
I know I'm a year late to this video, but in the meantime studying physics has made me gain an even grater appreciation of the metric system. The biggest problem with the imperial system is not conversion between different units of the same physical dimension (which I get that Americans don't do), but conversion between different dimensions. In the SI system of measurement, the unit of force is the Newton, which is defined based on the other base SI units as 1 N = 1 kg*m/s^2. Given this relation, it's really easy to derive a force from a mass and an acceleration, plus, even if you are given some measurements in a multiple of a specific unit (like being given a mass in grams instead of kg), it's easy enough to convert to their base units for your final calculation. This cannot be done easily in the imperial system, as, for example, the imperial unit of force most commonly used is the pound-force, lbf, where 1 lbf = 32.2 lbs*ft/s^2, so in any calculations involving force, mass and acceleration, you are required to convert your units. You might say that the imperial system also has the poundel, where 1 pdl = 1 lbs*ft/s^2, mimicking the relationship that exists in metric between the Newton and the base units, but, disregarding the fact that the poundel is not widely used, the unit of pressure is still the pound-per-square-inch, which refers to the pound-force, requiring you to do a conversion. Dimensional analysis is an incredibly useful tool in physics to see if you've messed up a calculation, and the metric system just makes it so much easier to do.
I agree but also all the really good physics has no units at all
.....People are not rocket scientists. You'll probably find more construction workers and regular people then people who spend their life studying advanced mathematics, science and physics.
At the same time, in engineering it is indescribably convenient to have your unit of force be the same quantity as your unit of mass times the acceleration of gravity which is something that gets lost a lot: metric is a system created in a vacuum where as imperial is a system created in practicality
more commonly i think i see the imperial system being made coherent the other way around, keeping the lbf as the unit of force and instead defining the unit of mass as 1 slug = 1lbf / (1ft/s^2)
I shall add the amount of times I messed something while studying because I didn't knew if it was a pound of force or a pound of mass.
in a practice round for debate I had to make the argument that the US Government shouldn't switch to metric and it went absolutely terribly (this was my second ever round so it makes sense) except for when my opponent asked, "how many ounces are in a pound?" to which I quickly and confidently replied, "16" and then my opponent asked, "how many pounds are in a ton?" to which I even more quickly replied, "2,000." After I said this my opponent got visibly red because the material he had prepared in response to my not knowing imperial units went to waste because I frequently spend hours learning the relationships between US customary units and have an incredibly good memory for random bullshit.
Your opponent could have easily shot back, "Wrong on both counts!" For you see, there are 12 ounces in a Troy pound and 2,240 pounds in a long ton. The former fact makes for a great riddle based on the fact that a pound of a precious metal (e.g. gold) weighs less than a pound of anything else, since the two categories are weighed using different types of pounds.

Personally, I agree that the metric system is superior, and the imperial sometimes gets talked down on. But what I believe to be the best system for measuring length is the Smoot system, developed by students at MIT
I went to high school with Oliver Smoot's son Steve. Steve eventually went to MIT and they measured the bridge in terms of him; I don't recall how his height compares exactly to his father's. I think it was pretty similar.
Fun fact: Smoot because the chairman of ANSI and later the president of ISO
Another complaint I often hear is that the pound is a measure of force where gram is a measure of mass, but the distinction only matters for those who have gone to space, or are in need of precision greater than 1/1000th (the variance across earth is about 0.7%). And even where the distinction does matter it's easy enough to overcome considering most mass is measured as the weight divided by gravity.
Also, while that was traditionally true, the pound-mass (lbm, the mass of an object whose weight is 1 lb at 1g of gravitational acceleration) has replaced the slug as the standard unit of mass in most imperial systems, to the point that the US Bureau of Weights and Measures defines the pound in relation to the pound-mass (which is defined in relation to the kilogram) nowadays and in many contexts lbm is just labelled “lb” and “traditional” pounds are explicitly marked as pound-force (lbf) instead. So that “problem” is going away...even if it’s created the new problem of did this person mean lbf or lbm when they wrote lb?
It matters to physicists, but physicists pretty much never use US customary units professionally. I can't speak for engineers. (That Mars probe debacle back in the day was about units of impulse, newton-seconds vs. pound-force-seconds, so I guess they were using pounds-force at the time.)
@@MattMcIrvin US engineers need to use a horrid combination of both systems because of companies that are too cheap to replace their legacy equipment that's calibrated in US customary and standards written that assume customary.

When you were talking about point size, as a graphic designer who works primarily with typography, I feel the need to say this. Points, picas, em, en, etc are convenient systems when you are looking at the proportions of typical use cases of typographic design. Typical length measurements aren't convenient with the way you design typographically. There is a reason we use them to this day beyond tradition.

My most controversial opinion is probably on imperial volume units. I support redefining a quart to be exactly one liter. That would make cups 250ml, pints half a liter, and gallons 4 liters. That makes it so people can use tsp/tbsp/cups for cooking, without needing separate measuring tools for metric and customary (or doing annoying calculations), it makes pints work well with liters (since they're used often in places like the UK from what I've heard), and the change would annoy people who use customary volume for exact measurements (which I think it good, they deserve it :p).

What I find interesting is the difference between Imperial and US Customary Gallons. The US system uses the Old English Wine Gallon, which is 231 cubic inches. It was standardized in 1706, and was the volume of a cylinder 7 inches in diameter and 6 inches in height. The Imperial Gallon, on the other hand, was defined in 1824, and was the volume of 10 pounds of distilled water at a temperature of 62º F and at an atmospheric pressure of 30 inches of Mercury. Two totally different methods of defining the Gallon.
Both systems of volume (at least down to Ounces) was set based on this definition, with both systems having four Quarts to a Gallon, two Pints to a Quart, two Cups to a Pint, and two Gill to a Cup. To compensate for the difference in gallon sizes, the Imperial system then claimed there were FIVE Ounces to a Gill, while Imperial had FOUR Ounces to a Gill. This means an Imperial Pint is 20 Ounces while a US Customary Pint is 16 Ounces. Oh, and the Ounces are slightly different between the two (28.413 ml for Imperial, 29.5735 ml for US Customary).
On top of all that, the US system ALSO has the US Food Labeling Fluid Ounce, which is exactly 30 ml, just to tie in with the Metric side of things again.
On top of all of that, alcohol is measured/sold in the US in millilitres/litres but served based (sort of) on ounces, it's utterly chaotic
The fact that imperial and US customary disagree with each other on units of volume drives me absolutely nuts. And hardly anyone talks about it, or even knows about it! One of the best reasons to go metric that I can think of.
That definition from 1706 means that the cubic inch and the wine gallon are definitionally an irrational factor from each other, which is quite funny to me.
I remember wondering why a pint of beer was going to be so expensive, then they brought it out, and I was like, WTF? That’s more than half a liter! This lead me to reading up about the differences while drinking at a pub. Meanwhile, our Maß was close enough to a liter that we now just declare it to be a liter, and it’s a convenient measure of beer here in Bavaria.

You are very correct in that ~30 cm is a very useful human scale measurement. Growing up in Sweden, the rulers we were assigned in primary school were 30 centimeters long. I still, 30 years later, sometimes think of lengths in "number of rulers".
Let's say I had a 50cm long ruler at home...
The standard ISO A4 paper size (296 mm) is also close to a foot.
The convenience doesn’t come from its scale but only from the fact that we had foot-long rulers and the supply chain that made them readily available. Same with the “19 l” jugs used with water coolers - they are actually 5 US gallon jugs. We could have 20 l jugs to round things up, but we just couldn’t be arsed 😂
Modifying established supply chains is hard.
@@danielbishop1863 and the other side is 210 and its actually 297.301 rounded to nearest mm. this is the formula 2^(1/4−n/2) where n is your paper size, for the short side 2^(-1/4−n/2)
I'm a carpenter, not an engineer, so let's get that out of the way. I will say that although I'm an American, I have extensive experience with both the Imperial and Metric system of measurement. Not gonna lie, I like both. It's easier for me to guess and translate the length of something that's not, like hundreds of feet long (see what I did there?) in inches, rather than hundreds or thousands of millimeters. Most of my experience (which is A LOT) in mm's comes from using European machines, and I quite like them.
However, if you really want to piss people off let's talk about using the cubit on a jobsite. It is effective.
But it's just plain stupidity to use "thousands of millimeters" use centimeters or even better meters.
Right, but that argument doesnt make sense, as stated by the guy above, you never have to use hundreds of thousands of millimiters, or even thousands, OR EVEN HUNDREDs, there are new, completely equivalent, mesurements about every power of 10. You can just switch to centimeters, then meters, etc

To be fair, metric becomes leaps and bounds more useful than imperial in the context of science. Defining a kilogram as the mass of a litre of water is actually extremely useful in most science fields, as water is by far the most common solvent in chemistry and also a good analog for flesh in biology.
It's pretty helpful for some everyday activities too, when baking most things have a density close to water.
It also makes finguring out some standard values and unit conversion factors possible when a look up table isn't exactly available (exams)
With the exception of celcius, though, which is just a worse version of Kelvin in scientific contexts
@@linoshcaalomar3951 it's not that bad, you just add 270-280 something to Celsius to find Kelvin and for everyday usage, Celsius is more useful imo
Bro nobody is saying that metric isn't better than imperial. Lmao these people
This makes a lot of sense! I grew up with the metric system and my stance has been for a while that in the age of smartphone calculators the difference doesn't matter anymore anyway as long as you have an intuitive understanding of what the units mean (so yes, I agree with "every system is arbitrary").
Also, I find the differentiation of distance (miles) and length (feet, inches) interesting because in practice I find that I do the same thing in metric. I use kilometres for distance and metres / centimetres for length and treat them as different systems, simply because I usually don't have to convert between the two (and yes, we also say "2.4 km" instead of "2 km 400 m").
Also, we don't exclusively use the metric system outside the anglophone world either. My shoe size in Germany is, e.g., 43 (≈9 in UK shoe sizes), but that doesn't mean that my feet are 43 cm long. In fact, I have no idea how long my feet are and I don't care to find out because even if I knew it, it wouldn't help me find a shoe. We also use points for font sizes instead of millimetres. My grandma also still used pounds (defined as 500g) for purposes other than body weight. I can't think of any other examples, but I'm sure there are, especially in old crafts that where there's not much interaction with engineers.
another thing I discovered when I visited France was that you still buy beer by the “pint“, except a pint is 500 mL (which is pretty close to the American and the English versions of a pint anyway, and is a satisfying serving of beer)
But it isn't it's kinda dishonest the way he portrays it.
The metric system isn't arbitrary, it was defined with a clear standard of conversion in mind, everything was made to be interchangeable volume, distance, weight, etc...
Everything is defined by the others there is nothing arbitrary about it, the only thing arbitrary is what they chose for the first one.
@@syzygy6 seems weird mostly a pint is 33 cl, and a half litre are called exactly that. You must've drank a specialty beer they useally come in more uncommon sizes
@@ThaGr1m He takes "arbitrary" as the opposite of "objective" here (this is implied when he says that metric is more practical but not more objective) in which case he's right simply because "objectivity" is not a property that applies to units of measurement.
I think his point here is that there's no "right" system of measurements, despite many people thinking so.
My main takeaway from this video as a whole life metric user is that, unlike in metric, imperial is precisely NOT thought through as well as metric when it comes to relations between distance, length, weight etc. and shouldn't be thought of as a closed system. That means he's still giving metric credit for being so interconnected, so I don't think he's misrepresenting it
@@quicksanddiver I get the distinction but I think he kinda maliciously makes a point of the abstract nature of measurement to counter the well thought out base for metric in an attempt to undermine a valid argument.
And this video for me comes down to I'm used to this so I don't see a usecase for all the good things you can do with something else.
If you want an example you say you're a metric user, this implies you're a non native english speaker.
We can use language as an analog here because there is nothing more arbitrary than language. I'm sure you've found the same thing as me when learning english that it is a language whit very defined nuances that give it a benefit in adjectives above whatever language you most likely normaly use. This to me is a clear benefit because it objectivly means you can convey more precise things.
Now for my native language( Dutch) we strap words together to be more descriptive(you probably have seen something similar with german due to meme's) so in theory we don't have a need for those descriptive words but that doesn't mean that dutch is as usefull and precise as english.
Same applies here people don't convert between systems because it's too hard, but there is a clear use in many cases they overlook
So as someone who is unfortunate to live in the UK, the single most frustrating thing about the "imperial system" is how different the systems (plural) are between countries. For example, we still use "pint" to refer to volume when it comes to beer and milk, with the value of an "imperial pint" being 568 ml (3 s.f.). The US (liquid) pint has a value of 473 ml (3 s.f.), which is about 20% off. Being someone who uses the internet a lot, remembering to do this conversion when talking to Americans is so difficult, and I hate it.
1 pint = 0.5L
@@appleislander8536 Near enough for jazz :-)
I've also been told that USA inches are smaller, but only by one person ;-)
The American Imperial system is much better, just switch to ours.
The uk is also fucked because we use an ungodly mix of metric and imperial units. We use pints for milk and beer, litres for soft drinks, gallons for fuel, metres for short distance, miles for long distance, inches for penises, centimeters for measurements, feet for height, metres for more height, grams for small weights, kilograms for medium weights, stone for some fucking reason and celsius or fahrenheit depending on how old you are. I don't think I have any logical reason to, but I choose to blame this on the monarchy.
In the Philippines we have become accustomed to utilizing both the SI and the US Imperial systems, partly as a result of past US rule in the country. The two systems are used side-by-side in everyday usage but for different applications. Even the spelling of SI units follow US English convention (e.g. "meter" instead of "metre")
We weigh things like groceries, produce and construction materials in kilograms, but the weight of people is expressed in pounds. Similarly, people's heights are measured in feet and inches, but lengths of objects and distances are measured in meters and kilometers. We use the phrase "six-footer" (>183 cm) to describe someone taller-than-average, and we like to eat "quarter-pounder" (~113 g) burgers at fast food stores. We refill our drinking water by the gallon but gas by the liter.
this actually makes sense is is really in the spirit of the imperial system, just using measurements for specific things that makes sense
@@GhostofTradition I think the US measurement system is better for more "casual" (i.e. non-scientific) applications or for measuring people, and metric for everything else. It's simply awkward and cumbersome to say something like a "one hundred eighty centimeter-er" instead of "six footer," for example, because one does not really need to be precise in referring to tall people. Other phrases and figures of speech such as "go the extra mile," "pound for pound," "the whole nine yards," convey their meaning much better as American units, without the need for people to consciously think of the metric equivalents to understand those phrases.
@@Theophan123 we just say one eighty meters
Here in Chile we also have quarter pounds
@vigilurbis3394 No offense but the examples you gave aren't very strong, in my opinion. Those are all just sayings that include these measurements because of the US's historical ties to the imperial system. But that doesn't prove in any shape or form that it's better or it "makes more sense". Especially when you realise that there are other languages in the world that aren't english, so even though "one hundred and eighty centimeters" sounds clumsy and long, other languages might express the same thing shorter. Plus then there's how most everyday speech omits unnecessary parts (such as the "metre" postfix because "centi" by itself is enough, or sometimes even the whole thing goes out the window, making the speakers rely on context).
With these two factors in mind, Spanish people clearly don't say "él mide ciento-ochenta centímetros", but "mide ciento-ochenta" or something, with the two o's bleeding into each other, further shortening the sentence when spoken. Or Hungarians don't say "száznyolcvan centiméter magas" ("he's a hundred and eighty centimetres tall"), but "száznyolcvanas" ("he's a hundred-eightier") or "egy-nyolcvan magas" ("he's one-eighty tall").
Bottom line is, whatever may sound bad in english doesn't necessarily sound bad in some other language. Plus, sayings are just... sayings. My native tongue is Hungarian and we have a bunch of sayings referring to times when people carved lines into wooden sticks to take note of sums of money but that doesn't mean we use/should use those.
I really like this video, you did a great job explaining yourself. I also think it explains the REAL reason that both systems are still used in conjunction today, feet and inches are convenient for human-shaped things. One thing you didn't mention is how they're good units for approximating, since they're based on a human thumb, a human foot, a 1/6 or a 1/5 of someone's height, etc. I use metric almost always in my life for things that require accuracy, but when I'm trying to ballpark a short distance, I almost always end up using imperial.
I know how long a centimeter is, I know how long a meter is... but most objects are smaller than a meter, and centimeters are so small, it's hard to visualize putting dozens of them front to back in my head. I know 30cm is approximately a foot, and an inch is approximately 2.5 centimeters. If my goal was complete accuracy, I measure and write in metric exclusively. If I need to approximate the size of something, I use imperial and convert to metric if necessary. I'm sure if my culture used exclusively metric I might be more comfortable approximating in metric, but we always use imperial for height, doorways, widths of a corridor, someone's weight, etc. It's a human-sized object, so we use it for things involving human proportions.
Also, most of the Anglosphere really has no justification for throwing shade at the US for not converting to metric, because here in Canada and most of the rest of the Commonwealth, we still use Imperial for the kinds of easy, human-sized measurements that that system is good for; we've held onto these units in common practice because they are legit useful, and we can take no legitimate pride in converting fully to any one system. At this point, the focus should be on redefining the Imperial units such that their metric conversion factors are less awful. The inch should be 2.5 cm, the mile should be 1600 meters exactly, the pound should be 450 grams, the gallon should be 4 liters, etc etc.
China actually went even farther, often quite drastically redefining traditional units to fit convenient metric conversion factors when they last standardized in 1930. Their foot-equivalent is exactly 1/3 of a meter, their mile is exactly half a kilometer, their pound is exactly half a kilogram, and so forth. That 1/3 of a meter system btw is genius, since it fixes one of the most glaring problems with metric, the inability to third things, by simply bolting on units for 1/3 of most metric lengths and calling it a day; as long as the two systems coexist and have such sane conversion factors it works marvelously well. Similarly, their pound is divided into 16 ounces before moving to powers of 10 in its further subdivisions, just so as to allow for the intuitiveness of powers of 2 to be felt on that particularly human scale, and if anything I think it's a shame that that wasn't also used for volume where it would probably be even more convenient... though my experience with Imperial powers of 2-based volumes in cooking certainly colours that impression.
Point is, having a human scale to systems of measurement is extremely valuable, and it's something the metric system systematically lacks, and it's something that can be added with simple and sane conversion factors with minimal fuss.
This is actually genius. And heck, all you really gotta do is redefine the yard as a meter, which is basically close enough, thus the foot as 1/3 meter, inches 1/12 of that, so on. It would probably still be utter hell to convert between mathwise, but it would indeed solve the biggest issue of metric, which is the absolute nightmare that thirds are.
Probably the first comment I agree with. Objectively thirds are a disadvantage of the metric system. We mostly aproximate and round when we have to deal with thirds (like in construction or woodworking) or scale up (in cooking for example).
But metric not being on a human scale? I disagree with that. 0 degrees is freezing, 20 is roomtemperature, 100 is boiling. A centimeter is a fingernail, a decimeter is a hand length, a meter is a stride. A kilo is a bottle of water as is a liter. A quater liter (or Viertele in German) is one cup of wine. 2 centiliters are a shot, so a centiliter is a small shot. A quater kilo or 250 grams is a stick of butter, 100 grams is a bar of chocolate.
And so on
Obviously alot of these associations have been established after the fact (the butter for example). It still shows that it is perfectly pheasible to use metric on a human scale, as a huge part of the world does it.
@@carlosdumbratzen6332 But does anyone use decimeters? In my experience, people tend to go directly from centimeters to meters, meaning there's no unit at a convenient size for, broadly, anything from "a handful" to "a person's height". Which is most of what a person interacts with day-to-day. Temperature - sure, freezing and boiling are more-or-less at convenient numbers (depending on air pressure), but weather and habitation is crunched down into a much smaller piece of the scale as a result (thermostats tend to go for integer degrees Fahrenheit, but tenths of a degree Celsius, because a degree Celsius is too big) and I'd say "do I need a coat today" is more common than "how close is this to boiling" - if you're boiling a pot of water, you don't do that by thermometer, you do it by eye, right? Specific temperatures outside the "weather" range are relevant for meat and baked goods, but those temperatures aren't particularly related to the boiling point of water anyway.
Volume and mass, I won't argue, because the only time I would actually have practical uses for those units is for recipes, and at that point the convenient size is "whatever your recipe and/or measuring tools are marked in". Whether milk comes in gallon, half-gallon (two-quart), quart, and pint sizes, or four-liter, two-liter, liter, and half-liter sizes is basically immaterial; it's all approximately equally convenient numbers and sizes and at no point do metric prefixes get involved in the latter case. Similarly for pounds and kilos, though I will admit to being surprised to hear that your butter comes in quarter-kilo sticks; ours comes in quarter-pound sticks (less than half the size), generally in four-stick packages, with the wax-paper wrapping marked at tablespoons for volume measurement for baking (eighths of a stick, so half an ounce, or close enough for the precision you'll be able to manage cutting butter by hand). A quarter-kilo stick of butter sounds like a pretty big stick!
@@qwertystop People usually say height in centimeters rounded to the closest so it's still basically decimeters
If you simultaneously define an inch as 2.5 cm and a mile as 1600 m, then you get an awkward 5333.333... feet in a mile. Though I suppose that's not really much weirder than 5280.
I never thought about how the imperial system is super easy to divide into halves, 3rds and 6ths. That’s pretty useful for construction and such.
A big reason why our system is the way it is, also is because of the fact it's really easy to reproduce without any kind of standard. The imperial ruler for example uses 12 inches, you can mark half, get 6, mark half again get 3s, and it's this reproducibility that made it very effective for such a long time. And at this point while metric is easier for maths and certain precision, the fact that imperial is tied to metric makes conversion very easy and thus forcing the change unnecessary.
Yes the main advantage of imperial measurements for daily use it’s just how easily they subdivided into nice even fractions. For example it’s much more comfortable to say a quarter pound versus asking for 250mg of something. The foot also divides out nice and easily too. The metric system is nice in some ways because it scales by tens however in daily life you really have to scale things by tens and also people aren’t computers
@@Mortablunt "It's much more easy to ask for a quarter pound than to ask for 250mg", because you, Mortablunt on UA-cam, have just unilaterally decided that saying "a quarter kilo" is impossible (which is 250g, not 250mg, by the way; 250mg is a quarter gram). We use "half a kilo", "a quarter liter", etc all the time. See, this is the thing with these "muh daily life" comments: People used to SI don't generally know how Imperial is actually used in daily life, and Imperial defenders, especially Americans, seem to be either misguided or willfully misrepresenting the daily use of SI. We do not talk about bloody miligrams in day to day life unless we tell the apothecary lady what dosage of a medication we need, or unless you work a job where these are the dimensions you work with.
"Imperial is more intuitive in normal life" is something said 100% exclusively by people who grew up using Imperial and have no experience with metric units and who are completely ignoring or not understanding the fact that this perception is exclusively due to habit. People used to metric units have the opposite experience. This is pure cope.

A few of the main reasons America hesitates from converting to metric is that:
1) We already sort of have in the cases where its significantly beneficial, like chemistry and physics
2) Americans understand and have internalized these units; I know what a mile is, but I think of a kilometer as about 0.6 miles
3) Some industries, such as metal manufacturing, pounds and degrees Fahrenheit have been in use for over 150 years, and that's what's stored in the records, and known to the employees. The transition in these fields could be borderline dangerous, or costly due to errors.
4) It doesn't really matter. Potato Potaato, a convention is just a convention. It just works.
Would metric help American industry better communicate with the rest of the world without using a calculator, yes.

The real lesson behind this video is one that is extremely important and I am sad that many will either not notice it or choose to ignore it anyway. You make a real effort to present the "other side" of the debate from yourself in its most clear, justifiable and sympathetic light, rather than presenting a weakened or (deliberately or just carelessly) erroneous version. This makes people you disagree with more likely to listen to you, as they feel respected and understood, so they may actually take the time to listen to and understand you when you explain why you chose your side over theirs.

my usual defense of the old imperial system isn’t really a defense of the imperial system at all, but rather of the value of using plural systems: nobody in practice actually uses “the metric system” for everything. every industry has its own special units developed out of convenience, and it’s preposterous to say that doctors are wrong for using “dose” or that arms manufacturers are wrong for using “grain” or that electricians are wrong for using “gague”. all units are arbitrary, and there’s rarely a need to convert between them. however, the beauty of metrology is that we can take any arbitrary systems and meaningfully convert between them if the need arises.

The US keeps using our system for most stuff because, it works well and we've been enforcing it for quite a while. We even have the Bureau of Weights and Measures to make sure that the scales and what have you are accurate. Which was not the case in most other countries that made the switch. SI was just in the right place at the right time when a powerful set of countries with poorly enforced standards could force it on the rest of us.

@Jordan Rouse Maybe not, but both the person in the video and the person you're responding to have no interest in giving the imperial measurement system any validity to exist and are simply interested in mocking it with their ignorance. That says more about them than it ever will about the Imperial system of weights and measures.
@@daexion wait? the video was making fun of the Imperial system? I thought he was being pretty generous with it.
If we had base 6 and kept the centimeter as it is, the meter would be 36 centimeters long, and therefore very close to a foot. Problem solved!
On a more serious note, the main plus point I have with the metric system is the easy conversion from one measure to the other. For example, the fact that I can weigh milk if I don't have a measuring cup is very handy.
the single biggest problem with imperial systems is that the units do not have the same values in the UK and the US
whenever Americans talk about fuel economy I always think "wow, your car must be so expensive to run" before remembering that the US has smaller gallons for some reason
US uses an older definition of the gallon as exactly 231 cubic inches. UK uses a redefinition from about a century later. That's why they're different, ours was actually first lol.
Historically, there were a bunch of competing "gallons", ranging in size from the Irish Gallon of 217 cubic inches, to the Elizabethan Ale Gallon of 282 cubic inches. The US ultimately picked the Queen Anne Wine Gallon (231) to be *the* gallon. And then the British chose a different one.
I find it interesting that in England, we use metric almost entirely but most people will use the imperial system when measuring height or weight of a person and we tend to measure speed and lomg distances in miles/mph. I don't know how common this is, but my family also prefers to bake in ounces.
Baking in ounces isn't very common these days, especially for younger people. But measuring jugs and spoons generally have both, but the spoons are indexed to metric (i.e. you will have a 10ml spoon and not a 2 tbsp spoon)
The word "mile" sounds a lot better than "kilometers". Kilometer sounds cold and artificial and the pronunciation does flow like mile does.
@@richardbloemenkamp8532in Sweden we have metric miles (10 km)
@@richardbloemenkamp8532define artificial in this context
Interesting - in Canada we use km/h, but we have the same issue for cooking (even worse, our ovens are in F, outside temp in C.) And height (I know my height in imperial, don't know it in metric. And I literally CANNOT picture what someone's height is in imperial, but I can if someoene gives it to me in cm.)
I always thought the reason imperial had such abstract convertions was because all of the measurements were different and someone decided to merge them all...
and I was kind of right?
Yes. Imperial measurements developed organically to measure stuff in a useful way. Arguably less "arbitrary" than the metric system. A foot is a large adult human foot. A nautical mile is one degree of latitude. A bushel is a...bushel. But those natural units needed to be standardized for trade since everyone had different sized feet.
@@p1xelat3d If you want people to be able to read that you're gonna need to use punctuation.
@@staalman1226 whats a punctuation is it edible
@@staalman1226 For the most part people can type without punctuation, and it still be mostly readable. It's when its more than one, or two sentences; That it can get confusing.

by the way, a lot of languages call inches "thumbs" since those were pretty good body parts to measure something small with (I.e. their width). And if you measure your foot using your two thumbs to run across it, you'll likely get that nice dozen. It's a nice measuring system for length.

I just tried that with my thumbs and feet. My foot is very close to 13 thumbs.
Most of the metric countries use inches for diagonal screen sizes for some reason. Your smartphone's screen is either 6cm×10cm (length x height) or 5'' (inches in diagonal from corner to opposite corner). The second one gets used more often for marketing purposes
My foot is 13 thumbs, you liar!
i have a 14 thumbed foot! interesting
as an irish person, living in a country where we all use decimal but are all surrounded by media in which imperial is whats used, this video sums up pretty much exactly my thoughts. we use a strange hybrid system based off of what feels more "human", ike the comment you made on the length of the foot. similar to the uk's saying-they-use-metric-but-not-really, except we do actually use metric for everything except informal speech. examples that id feel quite strongly about are that im not 189cm, im 6 foot 2 and a bit. im not just less than 13 stone, im 82kg. the shop isnt 800 metres away, its about half a mile, but the car goes at 120kmh on the motorway, not 74.56mph. its a pound of butter, a litre of milk, 16 degrees celsius outside and my pp is a certain amount of inches long, not any amount of centimetres. just my thoughts as someone in the small minority very familiar with both 🤷♀️
I definitely see though at least in Ireland imperial units are becoming drastically less common in informal speech aming younger and younger generations. It could just be where I live but I can only speak from my own experience. I'm 17 in Leaving Cert, I and most people I know *do* say the shop is however many metres/kilometres away. I still measure my height in feet and a couple colloquialisms here and there but overall that's about it. And then if you get to around my parent's generation, they do mostly think of speed in conversation as mph. They do think if their weight in stone and pounds.
So, continuing this trend, I can see metric replacing imperial in informal speech more and more as time goes by
@@lizardlegend42 tbh i agree with u ab that, was just saying how i see it at the moment.. im 18 lol just did my lc in june haha good luck
Did the Irish fastly convert because imperial reminded them of Britain
@@gamermapper actually we converted at exactly the same time the UK did, way later than most other places
@@lizardlegend42 Well, we've gone further than the UK. They still use imperial distances on roads. We converted to metric for distance yonks ago, and to metric for speed limits more recently. (Yes, there was a time when distance was given in km but speed limits were in mph. That's what I grew up with.)
