That would also break SI in pretty terrible ways. So we're stuck with some numbers that don't look pretty in base 10, but if that bothers you can look at all natural constants in hex going forward and then they'd all be equally ugly.

What physics constants look like is for the most part a consequence of a number of accidents of history:

- the fact that apes have five fingers on each hand

- the fact that we have two hands

- the order in which the various constants were discovered

- some of the base items used for early definitions (which made complete sense at the time)

All of these to some extent factor in to that odd feeling that things are not as elegant as they could be.
