It seems like a weird point to bring up. How often do y’all convert your measurements? It’s not even a daily thing. If I’m measuring something, I either do it in inches, or feet, rarely yards. I’ve never once had to convert feet into miles, and I can’t imagine I’m unique in this. When I have needed to, it’s usually converting down (I.e. 1/3 of a foot), which imperial does handle better in more cases.
Like. I don’t care if we switch, I do mostly use metric personally, it just seems like a weird point to be the most common pro-metric argument when it’s also the one I’m least convinced by due to how metric is based off of base 10 numbering, which has so many problems with it.
For evidence of the mile scale vs foot scale bit:
We have 2 measurements between that we don’t really use anymore. Chains, and furlongs most notably (8 furlongs to a mile, 10 chains to a furlong, 100 links to a chain, 4 inches to a link). The middle distance is just yards now. 50 yards, etc.
