I’m a digital age, all of that is converted automatically. Bottom right corner, units option. Even when you find suspicious values like 25.4mm (1.000"), there’s so much esoteric sizing out there that it’s not a smoking gun. We use 10mm hex sockets on 3/8" square drive ratchets and put 235mm wide tires on 18" diameter wheels across the world.
The other way too. Nobody has made a SAE bearing since like the 1950s. You will see bearings that are a somewhat odd size in metric, but they picked nearest measure to the SAE value asked for and then rounded to metric to not be as odd.
