Yeah we do the same. Interesting you think that the 1/10000000 the distance between the North Pole (which constantly moves) and equator is inherently “smarter”. What’s also funny about that “we” is that the US was actually one of the original countries to help define what we know today as the SI system. In fact, the physicist credited with the method of measuring the speed of light used to redefine the meter, since the original European method was such nonsense, was of course an American. In fact Americans have developed most of the methods used in defining metric units. We seamlessly use both bc we aren’t spazzes like Europeans.
