One of the things that I use calipers for is to transfer a measurement from
one part to another. I'll measure the size of a hole, and then use the
external jaws to mark a piece. I'd throw away any caliper that required me
to read the measurement, close the jaws, set the zero point, and then reopen
the jaws and set them to a particular measurement, which I'd've forgotten by
this point. The guy who taught me to do this (and also how to read a
vernier caliper) was a tool maker for decades; it's standard practice when
making things where absolute measures aren't important, just that things are
the same size.
