I hate the imperial system, it makes zero fcking sense. 180cm is a clear number, when someone says they are 5'11" that means less than nothing to me, they might well be talking in riddles. Same goes for stones, feet and yards. The only two things I can easily understand is miles because I've driven cars where the speedometer was also displaying miles. The other being pounds which I can roughly understand because weight plates usually have their weight embossed on them in both kgs and pounds.
The celsius scale is the simplest thing ever: 0= Water freezes 100 = Water boils over. The Fahrenheit? It's a completely arbitrary scale.
No, you order a 32cm Pizza, and an 5dl beer. Nobody orders in mililiters. Not even shots.
