I hate the imperial measurement system, and can confidently say that anyone who doesn’t recognize the superiority of metric is a freaking idiot. How nice it must be for you Aussies, Germans and Koreans to drill an 8mm hole, realize you need it a smidgen bigger, and yell down the ladder for a 9mm bit. Versus us Yankees drilling a 7/32 hole, then having to do an equation in your head to calculate if you need a 3/16 or a ¼.
