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.
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.
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.
