Great video - but something was forgotten to mention: 1. A cube with a side of 1 meter x 1 meter x 1 meter is a cubic meter (m³)! 2. The volume of 1 cubic meter corresponds to 1,000 liters (l)! 3. 1,000 liters of water weighs 1,000 kilograms (kg)! 4. 1,000 kilograms equals one metric ton (t)! 1m³ = 1,000 l = 1,000 kg = 1 t

temperature scale is still kind of arbitrary - you have to get yourself accustomed to bunch of random nubmers. what does 20 below zero means compared to 10? what's the room temperature, what would be ok and what would be kind of hot? what's the body temperature and what would be fever temperature? how hot is 50 degrees water as opposed to 40 degrees. what would be your cooking temps and oven temps for different recepies? and so on. there's no inherent logic in it. and those 0 and 100 degrees are irrelevant for the most part.

Did John Godfrey fly with Don Gentile? I lived in Piqua Ohio for a couple of years and was friends with Fr. Angelo Caserta,a Holy Catholic priest who was Don’s cousin,and he lived in Piqua until he died a few years ago,age 99 I believe. I thought I read that Don and John flew together. Thankyou!

+18 Deg a good temperature to set a room to in Winter -ve 18 Deg recommended for storing food in a freezer.

Antarctica is the largest desert and that’s not 40°C

I don't understand the American fixation with decimetres. Nobody uses those day to day.

Now we got to wait till they fix the time

Impresionantemente didáctico el señor que explica. Quiero hacer un aporte: el agua no podría llegar a tener una Temperatura de 150º C como se dijo, porque no hay más "agua" (líquida) sobre los 100ºC (se evaporará) Por éso los Estados posibles del agua son 3: 1 en forma hielo (a -0º C) 2 líquida (entre 1 y 99 ºC) y 3 gaseosa sobre los 100º C (vapor de agua)

Thats pretty much preschool stuff here in Gemany 🤣 Now you know why our engineers are ruling the world 😝

I travelled with Americans for a year and they constantly said temperatures in °F. Using °C all my life and knowing 0 is freezing and 100 is boiling, I couldn’t understand why you would use °F which isn’t based on everyday temperatures.

I have never needed to know any of this in 55 years, plus I live in The United States of America. 🙂

One joule of energy is needed to raise one cc of H2O one degree centigrade or Kelvin.

Next lesson: what do the Latin words mili mil deca deci cent centi mean?

One of the guys is high😆

Boy, if only boiling temperature would be like 100 or something this system would be perfect!

I'm someone who grew up in a metric-only nation and used to laugh at imperial measurements, I should say that a lot of the reasons some people prefer imperial still is due to its superior ability to divide evenly into greater parts than with metric. 10 divides into 5s and 2s, and that's it. 12 divides into 6s, 4s, 3s, and 2s. In most cases, measurements do not require such precision that metric is the only viable solution. While I personally still believe a standardized metric system for all would generally be more beneficial, I think many unfairly paint imperial as a completely useless system with no benefits whatsoever.

so when will America switch completely?

She looked confused when he said divide by 10.😂

As an American engineer, i use and like metric daily. I'm a big fan of Fahrenheit for environmental temperature though, sinply because it also works on a 100 scale. 0f being the coldest humans can survive with relative ease and 100f being the hottest.

I was hoping for calories as well, as in the energy required to heat water.

There are those who use the metric system and there are those who landed a man on the Moon... using the metric system...

people don't think in metric or imperial, they feel in metric or imperial. thank you for attending my TED talk.

The inch scale is a fractional scale, technically hexadecimal. Also there is a concept of "Soot" in Indian local terminology of measurements, where they describe 8 "soota" = 1 "inchi". We all know mm scale uses the decimal.

Remember: The Americans brought the first man on the moon but they did so by using the metric system.

Sadly the 40 degrees celsius have come to france in summer since the release of that video, and it's going to get hotter

"i know all about the metric system from my last job. I had a few grams in my pocket, a 9mm in my belt and a Kilo in my trunk." :Breadstickricky

How to bore a student by being "cute" . If you believe that a person doesn't know the metric system, 1) find out what system they are familiar with, and 2) do comparisons.

It's so nice seeing an American appreciating the metric system. He explained it far better than most people I've encountered, and I grew up in Australia where we always use metric and not many people understand imperial measurements. What a great teacher. Those kids were privileged to be taught by this guy.

OK quickly - how many sixteenths of an inch in one foot? And how many millimeters in one meter?

The fun part is when you start converting from C to F and people in the US who don't understand Celsius get scared when you mention that above the 49th Parallel above Montana/North Dakota we get around -40C or -40F for about 2-4 weeks in a row during the peak winter months in Saskatchewan. You can do the boiling water to ice in the air challenge in that weather, it's pretty spectacular. They just don't understand it enough or have a frame of reference until you do the conversions for them so they know 'hey, when it drops below 60F it's chilly here'.

thank you for making it easy for the US to join the rest of the world

Her eyes just glazed over. This is not a very compelling way of explaining it.

Who taught this guy ADR :P

yknow, in just about every professional setting I've been in in america has used metric instead of imperial and I rarely find anyone struggling with it. Its easy to use both imo and I rarely find myself in situations where I need to convert. Imperial I've found to be generally more convenient when cooking, as much of the volumes in imperial are in powers of 2, and provide a lot of really nice fractions that you don't need to think about at all, but in every job I've ever needed precision in, metric is generally preferred. TL;DR - metric is better for precision, imperial is better for quick approximation. No one needs to be elitist on either side.

What is this witchcraft?!😮

As an Australia that basically only knows the metric, did not know a lot of this, impressive video but for me, I always explain C as: 0C = freeing point of water and 100C = boiling point of water but as 0C does not = 100C, on the same cold to hot scale (you can touch ice fine, but not boiling water) for me I say 0C is roughly half as cold as 100C is hot, and you should think of temperature more on the 0C to 50C scale for weather on that 0-50C scale you basically have a prefect idea of how hot/cold it is, with the most comfortable whether being around 25C (the middle, give or take 5C for personal preference)

He explained it well. Just wondering if Liberia and Myanmar will switch before the U.S does.

Average metric fan vs Chad imperial enjoyer.

You should also mention that you need 1 calorie of heat to warm up 1 cm3 or 1 gr of water about 1K or 1 Celsius

It's funny, I went the other way around learning the Imperial System to operate MS Flight Simulator properly. I somehow always had the feeling using the Metric System in it was only "half the rent".

Distance between North Pole and Equator is 9944.35 km

Why this dumb bitch is laughing?

Took me over a minute to realize it says ALS not ASL. I was so confused why you'd want to defeat American Sign Language.

Statesians make the rest of the world passionate about metric. It's actually kinda strange.

In Australia we get 40 degree days every year, even in the none desert parts. I am not a huge fan of those days.

This is insane. These are basically adults but he’s talking to them like we talk to our 6 year olds in Japan.

No hate and all, but that's boring and I feel like only 1% got stuck. "The metric system is better - NASA uses it; every bigger company uses it; the whole world uses it. We should use it." "If you want to survive in the future:" "4 inches are about 10cm [=10.16cm]" "3 feet are about one yard" "1 yards is about 1m [=0.9144m]" "5 Miles are about 8km" / "1km is about 0.6 miles (100km/h ≈ 60mph [= 62.1371..])" "34 oz are about 1 liter -> this is 1liter" "2 pounds are about 1kg -> this is 1kg (the same thing)" -> 1. Exam with conversion of freedom units (inch to mile, water volume to pound, ...) -> 2. Exam with conversion of metric units (cm to km, water volume to kg, ...)

i have 20 cm tool

I have called indirect fire using both metric and what ever the fk the other one is. I got taught it and never used it. It was slow, much harder and only killed people...
