During the lecture at British university:

Lecturer: As you can see, taking into account solution pH change the sacrificial nickel cathodes will degrade at 13.2 mph
Me: Excuse me, what is this unit exactly? meters per year? It's impossible.
Lecturer: Mils per year.
Me: ...milil...
Lecturer: This whole diagram is American. One mil is one thousandth of an inch.
Me: Fucking Americans...
Lecturer: Yes, fucking Americans.

Has anyone ever here heard about mil? Apparently now to avoid confusion with superior metric system they call it 'thou'.
Hey, Americunts- what will you do when you need smaller unit to operate on nanoscale? Invent new unit? Equivalent to one 2450th of an inch?

That's because there are units of measurement between yards and miles that don't get used much anymore.

Also, metric is stupid because decimal is inferior to hexadecimal. I mean, if the scaling of units was based on a power of two it would be just be a matter of bit shifting. Of course, if we do that computers will end up switching to ternary to spite us or something.

Yeah, that's really arbitrary given that every other SI is based off of a physical constant of the universe. The meter is based off of the speed of light in a vacuum, the second is based off of atomic decay, etc.

Only the kilogram is based off of something that isn't a fundamental property of nature. Frankly it's intellectually dishonest to try and foist the kilogram onto the USA while portraying it as a "logical system." Not that it matters one iota because >>2636591 has it right.

Eh, not really. I mean, if you can't even come up with a good physical constant of the universe for mass then why should we switch from the pound to the kg? It's swapping one poorly defined unit for another. So the math is a little easier to to in your head, that might've been important back in 1962 when we didn't have pocket calculators embedded into devices that see daily use.

It gives us KG as a weight in the terms of EARTH GRAVITY, which means it is F=mg inside the scale, but then divide by g again, to give us the "weight" in a measure that is understood by "everyone" (except americunts).

It's just a semantics issue caused by the fact that mass can be used int he same was as weight in any situation where gravity can be taken as a constant. If you want people to take the distinction more seriously, I suppose the best thing to do would be to help develop space travel so that differences in gravitational force become a common enough issue for language to adapt to it.

>> No.2636841

The American length measurements may be arbitrary, but the SI length and time units are circularly defined. A meter is defined as the distance light travels in some fraction of a second, and a second is the time light takes to travel ~30e8 meters.

An OK compromise would be to take inches and extrapolate a system from there with exponents of 1000 - nanoinch, microinch, milliinch, inch, kiloinch, megainch, gigainch etc.

I can't believe this argument about weight and mass.

If you guys had an ounce of common sense you'd realize that weight is a function of mass and that for every day use, Kilograms can be and is used as a unit of weight. In unusual circumstances, the "weight" of something can be described in comparison to what mass the object would have if it had the same weight on earth.

e.g.: This rock, which weighs 38 kilograms on mars, has a mass of 100 kilograms.

The imperial system has take its root into society, regardless of how seemingly stupid it is. Building codes rely on it, and many people understand it. If you remove it outright, and replace it with something foreign, that causes far reaching problems in the areas that currently use it.
