    Number of fingers doesn’t have to dictate their number system. If they’re using a decimal based number system, then a decimal based measurement system is still the logical choice.

      It does though. Base 10 is entirely due to humans having 10 fingers.

          Base 12 is not organically common, it’s incredibly rare even with the modern counting systems we’ve discovered…

          The frequency of emergences (based on language families that use them) are: 4 ~1 time, 5 ~4 times, 6 ~3 times, 8 ~2 times, 10 ?? times, 12 ~3 times, 15 ~1 time, 20 ~9 times, 20+5 ~2 times, 23 ~1 time, 24 ~1 time, 27 ~1-2 times, 32 ~1 time, 60 ~2 times

        If we had 8 fingers, or 3 fingers, or 15 fingers, we would still be using base 10. It’s just that the value of “10” would be different each time

        Yes but (1) that isn’t the only base system humans use and (2) aliens could use a base system entirely divorced from their body parts. So number of fingers doesn’t have to dictate which base system is used.

      It partially does, the percentage of languages that use base 10 is nearly 100 and most that don’t use base 5 or 20… Sure there’s others (60 being the main one that still has an effect on most people’s lives) but they’re vanishingly uncommon
