It’s odd. As a old Canadian I was born in the British Imperial system with inches and gallons and bushels and pecks, but everything has been meters and litres and kilometres for many decades and I have adapted in some areas and not in others. The metric system just makes sense any time you are calculating. Gas mileage, for instance, ratios, conversions. But I have continued to use inches for woodworking because for the most part it is measurement rather than calculation and I’m mentally lazy. Though if I have to divide 2’ 7 7/16” into thirds, I’d reach for my metric measuring tape!
It doesn’t have to be an either-or. It’s trivial to just use another scale — maybe even fun to try: but maybe not buy the Starrett rules until you’re sure.
