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
If scales shouldn’t be arbitrary then a temperature measurement system that picked the state change of fresh water at atmosphereic pressure where you find a bunch of salt water which has a different state change temperature, might be just slightly arbitrary. Kelvin trys to fix it by moving the zero to eliminate negatives, but doesn’t change the scale making all the other temperatures arbitrary.
Metric is great, as long as humans are living on Earth. Any other planet or a major change to the atmosphere or Sea level and everyone is going to be why did they pick such random points. Luckily nothing is happening to change the atmosphere or Sea level on Earth so nothing to worry about.
