But it doesn’t use base 12. Take distance. Values smaller than 1/64" are measured using “thou”, “tenths”, and “millionths”, which are decimal multiples of 1/1000’, 1/10000", and 1/1000000" respectively.
Values between 1/64" and 1" are measured using dyadic rationals, i.e. base-2 fractions.
I’m not defending it, but it’s because 12 has more factors than 10
10 has 2 and 5
But 12 has 2,3,4,6
So 1/2 ft, 1/3 ft, 1/4ft and 1/6 ft all have a whole number of inches
Using a base12 system would only make sense if we all started counting in base12 too.
If enough people want that, i’d be down to start counting in base12, but i don’t think many people will lol.

Above 1" it’s mostly base 12,except for the yard.
