The conversion is kind of a pain in the a$$ but no one will steal it. Hell, no one wants to BORROW it.
I set my width, ride height, etc in multiples of pi so it all works out. I get strange looks from people when I tell 'em my car is 54.7 wide or 1.43 ride height, but chances are they were looking strangely at me already when I was humming the theme to Numb3rs while I was truing my tires to 3 so screw 'em.
When I first bought my Big Calipers I thought I would just use them for measuring rear track, but they have turned out to be so handy for a variety of things everyone borrows them and I'm always having to track them down.
I think I'll follow your lead and convert them to measure in pie. The only question now is Cherry or Apple
