I really don’t think that’s the issue. Even in the US, people complain constantly about the units. The stubbornness you speak of is actually more to do with not willing to accept the costs of the change. World’s largest economy can’t just change it all at once even though majority of the people support it. No one in the US argues that the Metric system isn’t superior. It doesn’t take a genius to figure out that multiples of 10 in a base 10 system of numbers makes everything easy. In fact, the superiority complex comes from non-US folks thinking “look at those dumb Americans and their stupid units”. Certain people think “Americans just don’t get it”. Are you content that US and majority of the countries drive on the same side? https://en.m.wikipedia.org/wiki/Left-_and_right-hand_traffic https://en.m.wikipedia.org/wiki/Left-_and_right-hand_traffic
