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.
Edit: After reading/responding a lot in the comments, it does seem like there’s a fundamental difference in how distance is viewed in metric/imperial countries. I can’t quite put my finger on how, but it seems the difference is bigger than 1 mile = 1.6km
I do stuff like this all the time. Like if i bought a pool i wanted to estimates how much water it needes to estimate all the follow up costs, if i am cooking something i often switch between kg and g, if am measuring things i switch between cm, m and mm depending on what i am currently measuring all the time. E.g. i needed a new working plate in my kitchen, i wanted it precut to fit exactly in after moving some cabinets while still aligning the sink. The whole space was measured in meters, but the individual cuts were all measured in milimeters. I was able to do all of that in 5 minutes with one piece of paper for sketching and my head. (And it fitted down to the milimeter in the end).
Or e.g. in my last appartment we had an weird electrical water heater that didn’t work that well. I was able to easily estimate the extra cost it procured by estimating water volume, temperature difference and electrical price, most annoying par was converting from joule to calories because it is not base 10. (would have taken >3years so not worth it for me)
