For people in Europe it is quite difficult to understand the mm / inch problems.
From my experience I can tell that it is a good idea to stick to one system, like the SI units in technical or scientifical calculations.
Or mm in technical drawings.
I think it would be a good idea to work with mm internally and convert them on demand in the GUI.
Or to omit the unit and interprete everything as numbers (a more mathematical approach), so the user himself has to take a decision about the units he wants to use. I'm working with a simulation program for system analysis, and I always tell my students that they must decide for themselves if they use seconds or minutes for example for the time scale. When they do this systematically, they don't have problems.
But I an new here and I don't want to push my opinion foreward. It was only a suggestion.

Does that mean I have it in freecad-daily when I update? (I'm not used to git things, still have to learn a lot
