You could start by calling it base twelve (because 10 would be too confusing.)

Or to really obfuscate called it base 10 (in base 12) :))

60 is a better base than 12. Even 30 would be better.

And we should drop the stupid Earth-centric metric system and go to some kind of Planck units.

Base sixty would be much worse for humans. There are too many digits to memorize, and the multiplication table is enormous. It does give you a factor of 5, but 5 is only so common because we use base ten.

Base twelve is better than thirty because you can represent 1/4 (0.3) and 3/4 (0.9) with a single digit.

We do, for physics. Very often c is treated as 1. The "meter" is really just a conveniently human-scaled unit, equivalent to the "degree" in trigonometry.

> 60 is a better base than 12.

And it proved itself useful on this Earth for probably longer than the decimal system.
