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.
This wall is 3 metres wide, how many 80 cm shelves can I put up on it?
This wall is 9 feet wide, how many 2’8" shelves can I hang on it?
I cam guarantee you’re likely to do the same thing I did, which is just “That’s really close to 1m shelves, so it’s 3 with gaps.”
I don’t know how many 's and "s go in a foot so ¯\(°_o)/¯
And no, I’d go 8 16 24 32, ah, too much, so 3.
