There is nothing inches-specific about the unit editor. What exactly is
your problem with it?

You might however be running into the resolution limits of GIMP. To work
around that, I suggest that you use millimeters where you would use
micrometers. You will have to deal with an extra magnification factor of
1000 then, but that's not much of a problem.
