I used to be very good with approximating small (<1 foot) distances via my hand span. But after retiring from a company whose motto is “Precision is our profession”, where measurements are down to .1 microns (3.94 millionths of an inch) that doesn’t quite cut the mustard any more. I keep one of their digital micrometers right next to me in my desk drawer.

Why can’t I choose more than one?
