I'm with you, I don't have the education yoy do, but I can obviously see what's easier. "Multiples of 10? No way man let's get weird with it, 12 inches is a foot, 3 feet is a yard (I don't even understand the purpose of a yard) and like 5280 feet is a mile. That's a measuring system we should use" also I know the US didn't create the system, but that's how I imagine it went down.
