Professionals have standards! Community for all proponents, defenders and junkies of the Metric (International) system, the ISO standards (including ISO 8601) and other ways of standardization or regulation!
It's actually interesting, an inch is the last knuckle of your thumb, a foot is your foot, a yard is one pace (left right left) a mile is 1000 paces
But for some reason when we standardized them so everyone's mile would be the same distance, we used a freaking giant.
Then pirates kept us from adopting the metric system
