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
Tbh I have never had to think about the pressure of my tires that way. I pump the bike tires until I feel they are hard enough, and cars come with stickers in it that display the recommended tire pressure for them. 0 calculations needed.
But if I had to calculate pressures:
The lb<->psi conversion only works on 1G environments.
Yes, most pressure calculations occur on 1G environments, but in that case 1kg=9.8N. which is basically 10N.
If my car has 3000kg of mass, it weighs 30kN. Now the math is just as easy as lb<->psi. With the bonus addition that I can easily differentiate “kg of mass” from “N of force” instead of “pounds of mass” from “pounds of force”.
