And a meter is one ten-millionth the distance from the North Pole to the Equator on a meridian through Paris, France. This makes more sense to you?
I have never traveled from the North Pole to the Equator on a meridian through Paris, France, and would have a hard time breaking up that journey into ten-million equal parts if I had, but my foot happens to be more or less the same size as that ancient king's. How about that?
IIRC, the inch used to build the Great Pyramid is one millionth of the distance from the north pole to the plane of the equator. Just a hair longer than the British inch.
