  • What would we get if we would switch to another arbitrary looking value? Also other units are based on other constants not just the speed of light, so at some conversion you would have to use similar strange numbers, you wouldn’t solve your problem you would just move it to elsewhere.

    And you rarely convert to lightyears, so the strange numbers are outside, and everyday units fit nicely together with base 10.

    And 1 liter or dm3 of water is roughly 1 kg, so the original meter is actually based on the density of water. It’s very convenient that you can convert between weight and length in your head.
