Is America Actually Metric?

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 This requirement was repealed in 1987.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)_/¯
Huge thanks to NIST, Ben Stein and Patrick Abbott.

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 so BS that it's is always stated that it's the International Prototype Kilogram (IPK) that has gained weight when in fact it's likely the one that has changed the least in mass. All the other prototypes are used A LOT more than the IPK and are also shown off like in this video even. It's likely that all the divergence of the various prototypes is simply down to poor or too much handling of them. Sweden has K40 and are very restrictive in it's use. It would never be shown off like in this video for example but always sits locked up for years between the times it is used. K40 is also the prototype that has changed the least out of all of them compared to IPK.

Yes, kilogram will stop using a real world object to define kilogram. Scientist all over the world trying to redefine it since 10 years ago or more. You can even watch Veritasium journey with redefining Kilogram. He have a video with the oldest 8 years ago about the topic. Edited: Ok, they already changed the definition, no more real world object! Long live the kilogram!

This is one of the stupidest things I have ever watched. The Imperial system was in effect hundreds of years before the metric system. Imperial measurements are in NO WAY based on metric measurements. Metric measurement are DERIVED from the imperial system - NOT vice-versa. This guy is an imbecile.

You guys (americans) should go all the way, I know change can be scary but it would be worth it.
Rupert Sheldrake asks the question why laws of physics, constants does not evolve while many are evolving? actually they are and their values evolve as seen in this example k20 and the others which are compounds and their values change by time and saying that it is an exception is not a scientific way of questioning a phenomenon. He will shine in next 50 years :)

How do they measure it? Gravity? I think if you wish to measure that in high precision. You should take altitude, air density & tidal factor in to account. They are small but it can affect the mass.

The buoyancy part seems weird. Does that mean two different materials having equal actual weights (but different volumes) may show different weight measurements due to differences in their volume? If thats true, then to truely know the actual difference between two objects, they should also be of the same volume!!??

Please the unit is the metre in French and English. A meter is a device, not a unit of measurement. Confusion source. Why create confusion? The US does nothing to promote metric yet questions the construction of a system they obstinately and obtusely refuse to use. Metric SAVES money. Is there any hope for the USA? Does anybody care now if they use obsolete Reagan-era units? In 1985 during NAFTA negotiations the USA asked Canada to stop metrication. We should not have. We suggest the US use Roman Numerals with the obsolete units. e. g. instead of 2,000 mL, M mL :-)

I have been to the United States of America and have found them using both metric and imperial almost seemlessly. There are a few things that they will never do both systems. They use Fahrenheit for temperature measurement most of the time and only rarely use centigrade. Length is in miles for the majority of measurements. But I found places using kilometers also. The rest uses both measurement techniques nearly seemlessly, especially in their mechanical tool kits. I know it is fun to mock them. But the truth is that they really do use both methods for the most part.

it`s funny how USA people think America is a country rather than a continent... actually is quite sad. Last time I checked America was a continent. American is the same category as European or Asian... please just stop thinking "American" means "US citizen". Argentinians are Americans, Canadians are Americans. When you realize that North America and South America are one continent for 99% of worlds population except for the USA you start realize how biased you guys are. Or you think eastern Europe is not Europe as well? Maybe that's why USA government treat SA as their backyard, and aid military coup d'etat in my region. Democracy is just a fake excuse that USA (not America, because I'm American and gladly not USA citizen) uses to invade other sovereign nations. And please understand that we do understand that a nation's government is not a nation's people, but you Americans have a historical debt with all South America that you invaded and tortured our people for being afraid of communism back in the 60s - 70-s and even today. So the least you, American citizen, can do is stop using American as "USA citizen". You are not the owner of this continent, and the major part of Americans never went the USA. cya

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.

The integral of the metric system is decimal. Therefore, the conversion of kilogram-gram, kilometer-millimeter is determined only by the decimal coefficient between units, but there is no change in the notation value resulting from the displacement of each unit. In other words, 1-meter and 50-centimeter can be written in just 150 centimeters. The preceding numbers 1 and 5 remain unchanged. This remains the same even when combined with other measures, eg mass. If there is a 45g iron bar at 1m, it will be written as 45g/m. If this is changed in cm, the expression value [45] in 0.45 g/cm is unchanged. But what about 5'8" in the pound-yard method? 5 feet 8 inches would be 5+8/12=5.6666666666....feet if unified towards the feet, If unified in inches, it would be (5x12)+8=68 inches. Either way, the value that was written on a daily basis is losing its meaning. So what happens when you combine this with the weight? It is impossible to predict a bit. Somehow, there will be a huge number of false expressions. Perhaps multiple units are needed. Yards and feet, inches, and pounds and ounces. The core of the metric system is decimal. This is different from the unit system we use intuitively. However, by using a decimal number that can be converted at any equator, we can grasp and apply many concepts that will disappear due to differences of opinion. The United States is not using the metric system as long as there is an inch ruler right next to the feet.

There is a country whose Mars Climate Orbiter was destroyed in 1999 "because a contractor provided thruster firing data in English units while NASA was using metric.” That country has realized that standardizing on the metric system is appropriate when landing NASA astronauts on the moon in the future. (Same reference.) There are people who insist on using a system of measurement used by only three increasingly isolated countries on the planet.

You say "metric system" but it is actually the international system of units (SI) which defines not only metres but also six other base units (kilogram, mol, second, Ampere, Kelvin and candela) of which all other units are derivatives (e.g. Joule is kg m² / s²). And today all SI base unit, also kilogram and metre, are defined by natural constants rather than prototypes.
