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.
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.
Does it matter whether you punch 3/8 or .375 into a calculator? Don’t tell me you calculate stuff by hand…
Trig is literally the math where you start dividing a circle in fractions and doing the math in base 360.
What the hell are you talking about?
I’m talking about trig using feet and inches. You know, rise, run, slope… Have you ever used trig outside of school? I don’t understand what you’re confused about.
right now i use it for waves and reflections. that’s all fractions and degrees. before it was machining and tbh for me that was faster to go to the book for the answers than calculate everything out.
truly trigonometry is a land of contrasts.
Ah nice, this should be a constructive dialogue between open minded and empathetic individuals.

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.
I may be biased, but I think it kinda makes sense. All the fractions are really just powers of two:
One half
One quarter
One eighth
One sixteenth
One thirtysecond
etc.Oh yeah, totally makes more sense to say “it’s 3/64ths of an inch” than “it’s 2 millimeters.” Completely reasonable.
So reasonable, in fact, that in most manufacturing that still uses imperial measurements they long ago abandoned fractions and moved to decimal inches.
Which leads to unholy abominations such as the wood shop sending over “cut off 3/64ths” and the metal shop cutting off 0.046875".
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.
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
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
In this thread: people bending over backwards to defend their insane, non-logical unit of measurement
Everyone focuses on why learning metric would be better in the first place, and they’re right. No one has come up with a good argument for me to throw away all of my measuring tools, convert all my recipes and relearn an entirely new system when the system and stuff I have works for me now.
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.
