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.
On ten-thousandth. The circumference through the poles is ~40,000km
over land or straight line?
