Well, of course, in the setup file, there is a parameter that specifies the number
of steps (or encoder counts) per user unit of measure. So, all you need to do is
set that to 1 (or perhaps .0001) to get the steps equal to the displayed (and
coordinates entered in the G-code) value.

You could also have a different setup file that mapped the steps to degrees,
when you weren't using it for exact clock teeth.
