Technically the metric system is "the preferred system of weights and measures for United States trade and commerce" as per the Metric Conversion Act of 1975.
You're just also allowed to use lbs and feet and stuff and most people do.
The versions of imperial measurements the US uses are even defined in terms of metric units, so they're less a completely separate measurement system these days and more just a weird facade on top of metric, even.
And in the sciences and drug dealing and the military, we use metric exclusively.
But for some idiotic reason, construction engineers often use imperial units and I have no idea why. Like buildings are built in pounds and feet and stuff, with half inch bolts and 2x4 (ish) lumber and half inch plywood. It’s idiotic.
I don't generally defend imperial, but feet and inches are actually really useful in construction. Base 12 is easily divisible by 2, 4, and 3. You often need to divide architectural elements in thirds.
I was a welder for years and I have to disagree. Using millimeters is way easier than inches, mostly because decimals are faster and easier to use than fractions. And it's not that hard to divide 10 by 2, 3, or 4.
As a former structural engineer who lived on a Jobber 5 all day, that's still pretty niche overall. Easier because it's what your used to maybe, but outweighed by situations where it's not. Try doing trig with fractions and then tell me imperial is better.
That might be somewhat useful if it was consistently applied, which it is not.
And it’s maybe useful for fractions, but how many feet are in a mile again? 5280? A square yard is what now… 1296 square inches?! Who the fuck is supposed to memorize all that?
What’s a 1/4 square yard in square inches?
That’s not easy, that’s putting the mental into mental arithmetic.
In this thread: people bending over backwards to defend their insane, non-logical unit of measurement
Alternatively, people insisting that Americans must be math gods for using such a demanding and archaic system.
Ah nice, this should be a constructive dialogue between open minded and empathetic individuals.

When my American friends insist that feet and inches is just easier for them, I just nod in agreement and give them measurements using rods, chains and furlongs as well. If you're going to go Imperial, you have to know 'em all. An acre is a chain by a furlong, totally logical as that would be 4x40 rods which is of course 43560 square feet. I guess it makes complete sense when your world is only a few furlongs across.
A truly logic system would be entirely designed around a base-12 number system. But we were born with an imperfect set of 10 fingers and that doomed us.
Those aliens have 6 fingers. It's an absolutely ironic twist that their discussion on measuring systems is super illogical for them, and yet logical is the verbiage they use.
Care to elaborate on how base 12 would be better than base 10 in this case?
Basically it's because 12 is more divisible than 10. Factors of 10 are 1,2,5 and 10. 12 has 1,2,3,4,6 and 12. This gives more flexibility when discussing numbers. Our time is technically using base 12, which is why we can say quarter past 4 and it means a traditional whole number. That's the argument I've heard anyway
I'll just leave this here: https://youtu.be/iJymKowx8cY
TLDW: metric is better because all the different kinds of units were designed to work together.
Where as imperial units developed organically, within specific trades/use cases. They're not all supposed to work together.
I use imperial because that's what I was raised with, but I recognize metric is better in many ways. My only gripe with metric is the gap in units between Centimeters and Meters. A foot is convenient size for most things.
Well buddy, you're in luck because today you get to stop griping about something that's been part of SI units for the entirety of SI units.
A foot is convenient size for most things.
Aka '30 cm', it's not hard to say. As someone from a metric country you just say the absolute cm value, or maybe 'half a metre', etc.
Jefferson actually intended to make metric standard in the US back in 1793. Unfortunately, the ship carrying the standard measurements from France was captured by pirates.
how about we all agree that the best system is american units with metric prefixes. After all it is obvious that it takes an hours to drive 318 kilofeet
When I find a wood working video on YouTube from the states it blows my mind how anyone can not just adopt metric “This is 5” 4/57 and we need to cut it to 5” 5/45 and a half” bzzzzzzz.
"Why do they use the much more complicated system?" "Nobody actually knows."
Those aliens have 3 fingers. A decimal system to them is like a system based on 14, 196, 2744, 38416, ... would be like to us - probably worse than US Customary
14, 196, 2744, 38416, … would be like to us - probably worse than US Customary
I mean if they had a base 14 numerical system then a base 14 measurement system would make perfect sense.
Contrary to that, the US does use a decimal system for numbers while the various units in the US customary system do not have any common base.
humans have used base 8 count the gaps between your fingers, base 12 count the joints on 4 fingers with your thumb, and base 26 by using lots of body parts.
Silly Americans, you could be measuring your winnies in GIGAMETERS and yet decide to keep using the kings thumb as a reference for it*
Base 12 is way more logical than base 10, I bet aliens would think we're stupid for counting in base 10 just because we have 10 fingers, my opinion on this is infallible fight me
