>>There's nothing natural about understanding either metric or imperial

That's not true at all. The metric system is more intuitive because it is a Base 10 system, which is very intuitive and natural for humans because we have ten fingers. Base 10 also makes things a lot easier because calculations are simply a matter of adding/removing zeroes/decimals.

10 fingers/base 10 isn't inherently any more "natural." There are cultures that use(d) base 12 (and count using the 12 finger segments on one hand) and probably others.

And base 12 is way more divisible.
