What I absolutely love about this fact is that America is still using British Imperial units. After literally having a war over whether or not the US should be independent of British rule, you're still holding on to our measuring system despite the rest of the world moving on.
Clam down, we are just talking about how measure systems. And the previous ones existed not because of cultural differences, but because every king and tyrant wanted to decide which stick their vassals should use to measure the world.
