This is all very nice, but we are using a decimal number system. It
is possible, plausible indeed, that a duodecimal (base 12) system
would indeed have been more convenient. However, that's water under
the bridge. At the time when positional notation was just getting
accepted, it was possible to go either way, now it is a bit late for
this. And, there are obvious advantages to having your number system
and measuring unit system coincide.
