Really interesting reply, and thank you for it. I’ve spent time in metric countries, and can, to a limited degree, equate either measurement to the other. Hell, I measure my vodka shots by the ml.

Before I enlisted, I had worked as a laborer putting siding on houses, and had to make cuts in both systems. I naturally default to imperial/avoirdupois, but given that most packaging has metric on it, I can still reference a can of soda as 355 ml. When I vaped, all of my e-juice was sold in mls, too.

Like being a polyglot, learning more than one language has its benefits, but if one has only ever learned one language, the likelihood is high that any other language encountered will seem strange.
