Don't be so quick to toss off that 16R-graduated ruler. 1/100"
measurements offer two advantages over mm. First, its resolution is
finer, 1/100" being 40% of a mm. (Depending on your age, corrective
vision may be required.) Second, it immediately opens a door from
factional inches to decimal (as do dial calipers and micrometers).
Now you have all that benefits of metric (decimal) without having to
surrender our Precious National Heritage, probably the most important
thing the British Empire ever gave us: the inch.
When I send hammer boring info to Wally Brooks, I give them in
decimal inches. He then picks up his digital caliper, dials in the
inches, hits the in/mm button and goes about his business.
