- The US signed the metre convention and bases all customary units on SI standards. As an aside, the Utah constitution from 1895 required the metric system to be taught in schools. This requirement was repealed in 1987. ¯\_(ツ)_/¯

Back in 1875 The US signed the Metre Convention, which basically committed the country to use the metric system. In return, French scientists sent two platinum-iridium cylinders that weigh 1kg to the US in 1889 (known by their designations K4 and K20 from a set of 40 identical objects that were produced and sent around the world). So even though everything you see and buy in the US is usually reported in pounds, all weights are traceable back to the K20 kilogram (by applying a conversion factor to get to pounds).
When I was in DC a few weeks ago, I visited the National Institute of Standards and Technology (NIST) and got up close with K20, which is still kept there and used to calibrate all mass standards in this country. I thought it was pretty cool.

"It's stupid" is not "the truth" though in any absolute sense, it's a balancing act that depends on different assumptions one makes and different time frames. E.g. if the US will exist for 200 years, then the hassle of switching is probably worthwhile. If it might only exist for 20 years, it's almost certainly not. Depends. So I would say he was wrong in claiming that unequivocably. (All the details before, fine)
having to transform anything from one system of reference to another then back again is so inefficient that it is, in fact, stupid. It does not matter what history, economics or logistics have to say about this. Imagine the "hassle" of changing the heliocentric paradigm... Who could've said it was "worthwhile" then? Objective Truth does not depend on context, that's why making it objective is such an important mission.

He forgot the most American measurement unit: football fields
😆
This was suppose to be a joke and it's an old one. They use football fields to give u a sense of reference because human is bad at imagining big number. It meant to give u an ideal of how big it actually is and it's good. I indeed hate US measurements unit because I never use any of it in daily life nor ever learn it. But this "football fields" thing, I actually like it.
Imagine having a specimen for a football field measurement!

they are lesser units, any person using imperial units are dumb and deserve to be ridiculed.
People who use imperial units aren't 'dumb', it's just what they're used to. The change to metric has to be governmental and slowly ( I mean decades slowly) adopted by the people. What is 'dumb' is every single justification I've ever heard for sticking to imperial.
+Lightbearer _I mean decades slowly_
Plenty of other countries have managed to switch to metric perfectly well. NZ started the shift in 1969 and was done by '76. I imagine things like the internet and manufacturing techniques would make the process quicker today.
I was basing it on here in the UK. We officially adopted metric in '65 but imperial still used in a lot of places. The difference being, I use more metric than my parents, and their parents barely understand it even now. This makes me think a conversion requires at least a generation to be done fully.
"It's stupid.."
"Are you allowed to say that??"
"Well, it's the truth!"
many people need to understand this..
How stupid? The metric system is just as arbitrary as the traditional system.
the point is that the traditional system is metric. Brits just wanted to be different because they had an empire and such.. Nowadays however it's kinda silly that the remnants of said empire refuse to just translate back to the system everyone else uses
The brits did not want to be different because they had an empire and such. Come on how am I to treat you seriously when you write this kind of ahistorical nonsense. The british had long used traditional units. They are mentioned in the Magna Charta for god sake. When the metric system came along they defined there units in terms of metric to make the systems compatable without having to go through the trouble of converting.
Nad: All of that is arbitrary. None of that has any relevance to a measurement system. Additionally, it is wrong. Nicky: if everyone used imperial, none of that would have happened, now would it?
Yeah and America should follow the rest of the world
1:19 as a US engineer, I can attest to that.
Ohh wow😂.
If that is true…why dictionaries exist? Metric is only for people who can only know how to divide ir multiply by ten.
I love this guy. He's amazing. "It's stupid". lol.
I'm Canadian. I lived in Texas for 6 months when I was 14, and attended my first half of grade 9 in Texas. Having spent my entire life in Canada up to this point, the metric system was second nature to me. When I started my grade 9 science class in Texas, I realized a couple of days in, that this class was actually about teaching the metric system. My mind was blown. If you're curious, I had an A+ in that class, and actually helped teach metric to my fellow classmates. It was a surreal experience.
As an adult with my own children, I find it shockingly difficult to explain the imperial system to my children. It doesn't make sense. 12 inches in a foot. 3 feet in a yard. 1760 yards in a mile. 5280 feet in a mile. 16 ounces in a pound. 14 pounds in a stone. 2000 pounds in a ton. 16 ounces in a pint. 2 pints in a quart. 4 quarts in a gallon. 4 ounces in a cup. 2 tablespoons in an ounce. 3 teaspoons in one tablespoon. I'm baffled by the lack of consistency in the measures; it's all over the place.
10mm in 1cm, 100cm in 1m, 1000m in 1km. 1000g in 1kg, 1000kg in 1 tonne. 1000ml in 1l, 1l is 10cm cubed, aka 1000cc. All even numbers, all powers of ten. So much simpler to work with.
At this point, I'm just shocked that the us was part of the meter treaty, yet is fully imperial still. Finding out all US imperial measures are actually converted from metric standards is shocking.
Yes it is crazy. Try this:
Put one ounce of cotton and one ounce of gold on a balancing scale. What would happen?

@@solna7214 no idea?
@@Esky_boi, in the first case, the gold tips over.
In the second case the cotton tips over.
Figure that one out…! 😁
@@Esky_boi An ounce of gold is not the same ounce as an ounce of cotton. Gold is measured in troy ounces, not the avoirdupois ounce used for just about everything else. A troy ounce is ever so slightly heavier than an ounce. But there are only 12 troy ounces in a troy pound, so it is lighter than a normal pound of 16 ounces.
FYI, there are 8 fluid ounces to a cup, but with so much to remember, its easy to miss. I remember by the 2 cups to a pint conversion and a pint is 16 fluid ounces.
It all began with the forging of the Great Kilograms. Three were given to
the French; immortal, wisest and fairest of all beings. Seven, to the
Germans, great miners and craftsmen of the mountain halls. And two,
Kilograms were gifted to the United States, who above all else desire
power.
But they were all of them deceived, for another Kilogram was made: in the land of French, in the grounds of Paris, the evil scientists forged, in secret, a Master Kilogram to be above all others. And into this Kilogram they poured their knowledge, their intelligence, and their will to define all the units in the world.
One Kilogram to rule them all, One Kilogram to find them, One Kilogram to bring them all and in the darkness define them.

There two kinds of countries:
The ones that uses metric system and the other that secretly use metric system to reach moon
Though, Mars Climate Orbitor...?
I think they openly used the metric system to reach the moon. And someone from a metric system-using country (von Braun) to lead them :-)
@@freibier NASA didn’t begin switching to metric until the 80s. Though there was a quirk with the guidance computer on Apollo where the calculations were done in metric, but the readings were displayed in US Customary. After that it was generally a mix.
The reason for that is because US Customary is still big in the engineering world in the US, though no longer universal.
Ahem.

Agree 100%. Why is nerve-wracking, distracting music, which often competes with the narration, the norm? Are people who post UA-cam videos so insecure about their content, that they think it needs "enhancement"?
Spoiler alert: the Kilogram will be defined via the Planck constant
Antimatter Putin The meter is actually based on the lenght that light travels in an specified amount of time. So its based on a universal constant "speed of light in vacuum "
As Alpha and Josué have said, meter and second are already defined based on physical constants (which hopefully will stay constant... but then again, does *that* really matter?). And the kilogram (to spoiler the next video) is being worked on... I think they do have it nailed down mostly, just need to finalize it treaty-wise next year. I don't recall (I've read of it) the definition they'll use, it might even be what LKAChannel says. :D
Kind of. It will be calculated via the Planck constant *measured on the basis of the existing kilogram standard*. However, once they calculate the constant, it's value will be fixed and the new kilogram based on that.
Scrolled to find the answer, thanks.
+Jurgen The second is actually based on the radiation of a certain cesium atom, not a physical constant.

@@Teporame and you're nothing more than a grumpy old brit
The metric system is delightfully simple to operate, and the Americans sensibly decimalised their currency from the outset, even if not weights and measures. Those of us of a certain age can recall with horror, struggling through long division of money in pounds, shillings and pence at school, with teachers of widely varying doses of patience. Then came dollars and cents, and the whole thing suddenly became relatively easy! But dentists and jewellers still use "grains" as a measure of weight, which is but another variant of the old system. Col, NZ
So even Americans think the imperial system is stupid.
Demon nope, just him.
The Americans who aren't wrapped up in blind hypernationalism and respect the sciences agree.
Demon yes I'm pretty sure at this point alot of us do

Red Light Wrong they are part of it, not using it

I prefer inches and feet. Inches are big enough to have a visible impact. Moving something 1 inch on your wall produces a noticeable effect -- unlike say 1cm. Feet being base 12 can be easily divided into 1/2 or 1/3 or 1/4.
The issue of the number of feet in a yard or mile is irrelevant because in real world use you NEVER convert between those. In normal day to day life, I've never once needed to convert feet to anything else.
"My measures! Gollum! Gollum!"
THANKS! This video will always be my answer to any conversation about metric system in America.
Since 2019 the definition has changed:
The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015×10−34 when expressed in the unit J⋅s, which is equal to kg⋅m2⋅s−1, where the metre and the second are defined in terms of c and ΔνCs.

So many medication errors occur in patient care because of conversions between kilogram and pounds. To convert, you have to multiply or divide by 2.2. 1kg=2.2lbs. Since many medications are weight-based, if someone accidentally puts in a patient chart the opposite number, then a patient can get 2 times the medication they should. Either that or they only get half the medication they were prescribed. This can be extremely dangerous. We should just use the metric system. How would we go about switching?

Raul A.R it's not so metric system came in way after imperial did and most countries use metric even scientists in America for records use metric eg. payload is measured in kgs not lbs(lbs is just to inform public)..... weirdest part is UK uses both....in my case, india we uses Metric and so does Australia but why does UK who basically gave this system of measurement to her colonies use both...... baffling
I remember back in the late 70s, or maybe early 80s, we were all taught metric in school, alongside imperial. All our rulers had inches and cm/mm on them. We had to use both. We also used grams alongside ounces. The teachers seemed to think the US would eventually convert over.
But later, most schools stopped doing that, and laziness prevailed. Now, anything metric is more an anomaly. As a woodworker who likes European and American tools, I'm always using both.
I was in Canada in the 1970s when they officially went metric.

The silence at 1:00. Epic.
That goddamn cliffhanger. I'm guessing by the amount of atoms of a specific element?
Yes, that is one possibility. Another one is to use quantum effects on electrical circuitry, and it's only gonna get more complicated with more words.
Well, just like a meter is now defined in relation to the speed of light through a vacuum, and a second is defined in relation to the amount of decaying atoms, surely a kilogram will be defined in relation to some kind of fixed energy, like X amount of fotons with a certain frequency.
It's going to be based of Planck's constant h. But then, it will mean that kg will be defined by metre (distance) and second (time). Metre will be defined by speed of light, and second will be defined by Caesium.
funny thing is, this guy already made a video(back in 2013) about the new definition of a kilogram
I might be wrong but I think while second is defined by decaying atoms they aren't measured by that. They use a specific laser's wave length for that.
Great Video, Jimmy!
The only reason why imperial continues to persist in the United States alone is because many industries don’t want to spend money converting and the government (most likely on behalf of those industries) has made metric “voluntary”
So in schools it is really up to the class curriculum if metric is taught instead, and I suspect many parents have influence on wanting their kids to stick to the antiquated system. 1 big problem:
The United States can’t keep using two competing measurement systems for too long, especially with tech industries being more global and hiring international workers on special visas who naturally understand metric far better than most Americans.
Use of metric has always been voluntary in the US until recently. Nowadays, some government work requires metric. I think NASA is entirely metric now. It has worked out well enough being voluntary, in my opinion. Our automobile industry uses metric hardware without ever having been told they must. Businesss will do what makes for good business without being forced.
Everybody knows this quote(maybe not) :
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 **** yourself,’
because you can’t directly relate any of those quantities.
This is a strowman argument. The ratio is not exactly one nor do you ever have "pure water". In the metric system, we have to use material tables as well, normalizing them to water is of limited use. The true strength of the metric system is, that we all agree that 25.4mm is precisely one inch. A one inch piece of wood on the other hand can be either 25mm ("about an inch" - hidden metrification) or 25.4mm or "something around that". Those "cutting loses" and "rounding errors" add up quickly (but are partially the reason, why US engineers are much faster in calculating a rough result in their head, then other engineers with calculator take much longer to get the result to three significant digits).

The US should do what the UK done, introduce all packaging and products to dual weights. While keep highlighting the metric weights. Until the populace becomes comfortable with both, easily switching without computation. Then slowly phase out Imperial. I am fluent in both weight systems. A pint is still a pint in the UK.

Nice video like usually too.
Borsa The imperial system is older than the metric system. The imperial system isn't defined by any terms of the metric system.
*WAS* defined independently from the metric units. Keyword there is *was*.
When I went to high school I studied the Imperial units and memorized the inch as 2.548... cms... I used to know 5 decimals. Check it now on google or wikipedia or wherever. An inch is now precisely 2.54 centimeters.
That's because the inch (like all the US Customary units), which used to be independently defined and as such had weird ratios with lots of decimals vs SI units, have been redefined. Oddly, they've been that way since 1959 but our high school book in 1993 still used the old standard for the US.
There is not (no longer) such thing as an official specimen to measure to know how long a yard is. A yard is defined as 0.944 meters.

Originally, the imperial system wasn't defined based on the metric system, but now it is.

The redefinition in 2018, if you're too curious to wait.
Wikipedia:
In October 2010, the CIPM voted to submit a resolution for consideration at the General Conference on Weights and Measures (CGPM), to "take note of an intention" that the kilogram be defined in terms of the Planck constant, h (which has dimensions of energy times time) together with other fundamental units.[59][60] This resolution was accepted by the 24th conference of the CGPM[61] in October 2011 and further discussed at the 25th conference in 2014.[62][63] Although the Committee recognised that significant progress had been made, they concluded that the data did not appear sufficiently robust to adopt the revised definition, and that work should continue to enable the adoption at the 26th meeting, scheduled for 2018.[62] Such a definition would theoretically permit any apparatus that was capable of delineating the kilogram in terms of the Planck constant to be used as long as it possessed sufficient precision, accuracy and stability. The watt balance (discussed below) may be able to do this.
Christian Fieldhouse Thanks
Giorgi Gzirishvili sick! thanks for the link
layman explanation plz
it will be measured in terms of the planck constant, which is the smallest possible thing in the universe, and therefore the most accurate. Not sure how they're gonna do this however, as no measuring device can be accurate to a planck unit.
SirDomin8r123 Being accurate to a planck unit is unnecessary. as long as they are accurate "enough", it's fine.
There is an error at the density table @4:31, Iridium density is 22.56 g/cm3, not 22.65 g/cm3 as described.
Osmium is the top material on density.
I feel like the relative changes between masses of the kilograms (and the sudden stop in changes) could probably be explained by improvements made in measuring tools and manufacturing tools since the originals were made. It's not that they were gaining or losing mass, but that the prototypes made in the 1880's weren't made as precisely as we can now measure, and that increase in precision is simply revealing their imperfections.
You are probably right.
Reasons to use Fahrenheit and Imperial system:

well thats a stupid claim since it started out on the left with horseback, people would have a sword on the left hip, then napolean wanted to swap sides to show he wasnt like the monarchy which he spread over Europe(and then made himself emperor and brothers kings). Also the right eye is dominate for most people so its better to drive on the left since you can see more of the road with the stronger eye (but it doesnt really matter)
But when you drive on the right you sit on the left side of the car which puts your right eye closer to the centre of the car letting you see more of the road, doesn't it? :7

It's also easier to use your more weaker hand steering. It just needs to go up & down. Then you free your right hand to make more complex tasks by the panels/gearbox.
Fahrenheit is objectively a better system for describing the way humans experience the temperature. The temperature range in most habitable climates fits neatly between 0 and 100, and it maps intuitively -- 0 is extremely cold, 100 is extremely hot, in the middle at 50 you'll want a light jacket. Celsius is horrible for weather if you didn't grow up with it.
In Celsius. Water freezes at 0 degrees, water boils at 100 degrees... Don't see why you don't use it..
1kg = 1 litre of water = a box of 10cm x 10cm x 10cm of water. 1,000litres of water fills a volume of 1m x 1m x 1m and weighs 1 ton
Yes and no ...
No. 1m x 1m x 1m of water weighs a tonne.
No, tonne is just metric ton. This ton vs. tonne stupidity is legacy of Imperial units… So everywhere on the planet metric ton is a ton, just in USA, possibly UK you are having these issues…..
short ton (2000 lb) metric ton (1000 kg) or ong ton (2240 lb)?
Why ton? Why not Megagram?
I worked hard earning my hard science degree so am a total full believer in the metric system over the standard system. It's amazing how many people argue for the standard system being easier to use therefore better than the metric system. Of course this perspective comes out of ignorance and fear of the unknown.
I on the other hand find great pleasure in working with the metric system because its based on logic and reason. One kilometer = 1000 meters, 1ml water (at standard conditions) = 1 gram, 1000 grams =1 kilogram.... a truly amazing system. Thank you France!
I hope all these amazing artifacts are protected against earthquakes and other potential disasters!
Yeah my scale at home is definitely not accurate then...

I had to stop at 1:17 and revel in this fact. I heard as a child about the metric system, and again we 'played' with is when I took a cooking course, but I truly started to use it when I joined the U.S. Army, and now that I've been living in Germany these, oh past 35 years, it comes naturally for me
This information feels like the american public is being treated like children; (we're using Metric, but we'll leave the imperial labels on, so the public doesn't have a hissy fit)
Does the $100,000 Kilogram come with free shipping?
Only with Amazon Prime.
Only if its under 1 kg. Would you like us to remove just a bit for free shipping?

Wait a minute, you are telling me that the *Quarter Pounder* has actually been a *Royale with cheese* in disguise all along and *not* the other way around ???
Also, I now want a *Bootie Butler* for no reason.
Be careful not to mix up the *Royale with cheese* with *royal cheese*, which is the stuff under Prince Albert's foreskin. #HYBPA
fake news. here in a metric country (thats all but 3) that speaks french theyre called "quart de livre avec fromage"
@YTViewer , lol the movie reference sailed right over his meme head.
The quarter pounder has been a 113.398093 g burger for over 100 years :D
There is actually a metric "pound" not as a defined unit but in common language. It is half a kg, which makes a quarter of that 125g. So a metric quaterpounder is actually more than an imperial quarterpounder, about 10% more to be precise. So our european quarterpounders are bigger then the americans.

Well the originals are probably priceless. The new ones are 100k
Original are "Priceless" because of added cultural value.
New ones, despite being made from the same materials, are much cheaper.
This is antiquariat for you.
@@Rybakov22 True. Of course, it's also because as time progresses, some materials are easier to mine due to better innovation, while other materials are harder to find because we're running out of them in nature. Then there's inflation.
FANTASTIC !! US was metric since 18 hundreds !! I could never wonder that. Btw, Dr. Abbott is very nice. Very didactical video, thanks for sharing;
He is not a PhD.
You mean: "the American 2.20462262 Pounds"
Zohar Cochavi pounds are proportional to newtons, not kg.
The bloak said that imperial units are defined in terms of metric units. Why would a measurement of weight be defined in terms of a force, which in itself is defined in terms of metric (SI) units and thus the kilogram. Seems pretty far-fetched to me
Zohar Cochavi bloak?
I'm sorry for using that word/term xD
I mean dr. Patrick Abbott
The Wikipedia article 'Pound' refers to a pound as a measurement of mass and includes this citation:
The yard or the metre shall be the unit of measurement of length and the pound or the kilogram shall be the unit of measurement of mass by reference to which any measurement involving a measurement of length or mass shall be made in the United Kingdom; and- (a) the yard shall be 0.9144 metre exactly; (b) the pound shall be 0.45359237 kilogram exactly.

Mass is supposed to be a method of substance definition, which is independent of gravity/weight. The planet has been increasing in mass and therefore in gravity. Mass needs to be able to be defined in terms that do not rely upon gravity.
American schools use Celsius or Kelvin when measuring temperature
American nutrition labels use grams and Calories (same thing as Kcal)
The metric system is one of the best legacy of the french revolution to humanity
Just about the only good thing to come out of the French revolution and its aftermath!
(And in reality, most of the work was actually done before the revolution.)
You forgot about choping head off bourgeoisie.
Peter Lund the best legacy was actually the french civil code. It was a turning point for all legal systems in the world outside of the anglo-world (yes, they are always swimming against the stream).
And Bistros.

I work in Weights and Measures in Illinois glad to see videos out there giving folks an idea of what we do.

Thank you for observing a less than pointless arbitrary unintentional pun.
My job here is done.
oboi oboi that pun actually hurt me mentally and physically
Planck's constant
The researchers placed a known mass on one end of the scale and then counterbalanced it by sending an electric current through a movable coil of wire suspended in a magnetic field. They then used that electromagnetic force to measure Planck's constant down to an accuracy of 34 parts per billion.
But if you do that, that defined mass is therefore defined in kg itself and therefore depends on the constant itself which wouldnt work.
"Are you allowed to say that!?" ".... it's true...." i like this guy :D
love it, dude reping the steelers lanyard.
I manage building construction for a living and wish we would use metrics. It would be an easier system.
weedandwine Same, from the land of heat pumps.
100 centimeters= 1 meter and 1000 meters=1 kilometer. 1000 grams=1 kilogram and 1000 kilograms=1 metric ton. There... ya'll know the metric system now. Everything is just more zeros, it's that easy.
1000 Kilograms can also be called a Megagram
Actually a lot of things are measured in millimeters (mm) so we can divide by 1000 from the standard meter, just like we do with the weights.
Not everyone is so dumb they can only work with base 10 conversions.
@@DrD0000M But you've gotta admit, base 10 makes the math a lot simpler
@@DrD0000M It isn't that we can only work with base 10, it's that it is far simpler, easier, quicker and gets it out of the way so you can do more important stuff. That and every single person can very easily do base 10.
2:53 where did you get that map of Paris ? Not quite sure, but it probably was printed prior to 1920. As it shows a belt of fortified walls ("Les fortifications") which ended being fully demolished in 1929, after nearly a decade of efforts.
I invite everyone staying in Paris to take a ride in the beautiful garden surounding the storage bunker of the prototype-kilogram, in the parisian suburb of Sèvres ("say-vre"). This park, named Parc de Saint-Cloud ("sain-kloo"), is one of the cutest exemples of XVIth century countryside-like gardens, with their typical "à la française" designs (geometric shapes, showing "the dominance of Man upon nature"). It used to be the home of "Monsieur", brother of King Louis XIV, and is now a public park with lots to see and enjoy.
The BIPM (Bureau International des Poids et Mesures = International Bureau of Measures and Weights) ; the nearby Manufacture royale de Sèvres (a school and "living museum" for the finest in arts and craft of ceramics, producing to bestest of them) ; the sports club Le Stade français (founded 1883, featuring 22 different sports from track-and-field to rugby or rowing) ; several gastronomic restaurants ; "La Grande Cascade" (a huge garden waterfall, legacy from the royal era) ; the annual "Le Grand feu" (largest fireworks event in Europe, as a tribute to those set up by the "Sun King" Louis XIV), etc. etc.
The Parc de Saint-Cloud is a must-see for anyone enjoying the nicest places. And even tough not exactly in Paris, this place is contiguous of the capital, with bus line 72 going straight to the main entrance grid of the garden... can't be any easier, just a 45 minutes ride from the Hotel de Ville (Paris City hall) or Place du Chatelet, or 25 from the Tour Eiffel (you all know about). Such a ride for the price of a bus ticket... how about it ?
Hope you'll have time to see the "kilogramme-étalon" (litteraly the "stallion-kilogram") next time, live in the basement of the BIPM.
This concludes our little "touristrium" interlude...
Great video, as always !!!
So before the kilogram was redefined, a change in mass of the physical Standard Kilogram meant that everything ever weighed suddenly had a different nominal mass. Kind of like everytime the US dollar gets inflated by the FED, all prices worldwide (in all other currencies as well) go up. We really need to redefine money in terms of some physical constant like with the kilogram (it used to be mass of gold).
Well it's more like you have less money than before if that happens. The issue is that all money that is owned is only nominal, and not fixed based on its value. There are however "global" monetary units, WCUs, that attempt to fix it based on the average GDP.

Well , i do travel a lot and from time to time i go through the US and so far they've been very professional. Sure there's idiots everywhere i guess...
A little knowledge is a dangerous thing. Perhaps someone confused Iridium with Radium, which is radioactive.
Certainly my generation in UK are happy to use any measurement. In my draughting days we used both, depending on the customer.
If i measure something and it's 6 inches i will use that. If it's 150mm i will use that, whatever is convenient for me to remember.
For instance UK flloor tiles might be 1 foot square, but box will say 305mm square because law says must be sold in metric.

You should do a video on how every si unit is defined
I think Sixty Symbols has already made that video.
1 inch was originally defined as the length of 3 dried barley grains placed end to end. They just later updated it to be based off of the glorious metric system.
1:18 THANK YOU that I was saying about those units all the time .
I love how he says that to this day the kg is defined by the big K , but they just changed that yesterday :D.
What a great narrator!
Metric system ftw

Cyberdyne really should've beefed up their security measures.
I live in America and I actually grew up with the metric system, the only imperial measurement I can really estimate well is miles per hour, I really think its only a matter of time before we start using metric for everything
@Mac's Music & Art I can't help but feel like that's a friend problem and not a measurement problem
I am subscribed, but I did not get the answer on the last question of the video - how it was redefined...
Imperial is ancient and dated. It shouldn't be used anymore. Using different units for measuring short or long distances (inches/feet/yards/miles) or weights (ounces, pounds) or volumes (cups, fluid ounces, gallons) just doesn't make sense when they aren't easily compared/converted (How many feet in 0.5 miles? How many yards in 2/5th of a Mile?). With metric, it's very easy, even with more complex fractions. I know it's difficult to change, but it needs to be done, especially when there are only 3 countries in the world who still use it.
Doriandotslash here in America it's simple to us. Since most people don't need to use metrics in their daily lives and are use to imperial then there really is no need to change because why should we if we don't have to. I mean yeah we use metrics here and there like in science and math class so it's not like we're completely unaware of it
Shiny Kingdra
It would make construction way easier if we all use the same units between the civil, architectural and mechanicall designers.
We don't use Imperial in the U.S. We use the U.S. customary units.
Imperial is as ancient and dated as the metric system!
even better, the US needs to be so special, that they invented their own measuring system to make sure they stand out.
which is basically the way the States think about everything in the world, fortunately many people are turning around when they find out their ways aren't superior. now if only the governing bodies around the world learned that
Hi, Derek!
