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
That is in fact incorrect. And the reason is in that other comment. To make a summary of that other comment:
If an only-metric guy wanted to communicate with an only-imperial one, each would need a table of conversions. For a basic use case, the metric cheat sheet would only need 8 entries, while the imperial one 10. That is, you need to memorize less "magic number"s for metric than for imperial. Furthermore, 5 of those entries in the metric cheat sheet are: 1000, 1000, 1/10, 1/100, 1/1000, which are obviously easy. So the real difference would be more like 3 entries to 10.
Of course, any kind of real measurement you will need a calculator. But that is reality for any unit conversion across systems. The difference is that you only need to remember 3 numbers to convert to/from metric, but you need 10 to convert to/from imperial.
