      Yeah, but does the kilometer have a cool origin like the mile? Checkmate math nerd.

          Yeah but earth is wobbly and imprecise so now we define the meter as “the distance light travels in a vacuum in 1/299,792,458th of a second”

            That’a a cool definition. I wouldn’t call it an origin though, that would still be the Earth measurement through Paris, which is also cool.

      Fun fact: there’s quite a lot of countries that use “mixed metrics”, with no real rhyme or reason for what uses old ancient imperial and what uses new shiny metric

      UK - Miles for long distances, switch to meters for distances less than a mile, always use km in air and sea. Milk in pints, petrol in liters, water in ml, beer in pints. Human heights in Feet Inches, building heights in Meters. Human weights in a unit even Americans don’t use anymore (Stone), animal weights in kg/g.
