Hours being base 12 is why time is way more painful to calculate with than other quantities, and why SI just sticks to seconds.

Would Americans love pre-decimal British currency? All those shillings and florins with lots of integer divisions? I bet the average metric hating American would be unironically demanding decimal currency back when faced with it.

I always get curious about how American construction works when I hear this argument. Do builders spend all their time dividing stuff into 3 rather adding, multiplying or subtracting? I would've thought adding a sequence of measurements up would be a far more common operation.

What happens when you need to divide something into 3 a second time? Or you need to divide an arbitrary length into 3? Or what if you need to divide into 3 sections, but there is something extra between each section (like a frame or a post), or you have to account for the width of the cuts etc?

Is an 8x4ft sheet (eg plywood etc) really easier to mentally divide into 3 (on either dimension) than a 2400x1200mm one?
