I'm reminded of this (comical) guide I first saw posted on Reddit: https://www.reddit.com/r/coolguides/comments/e1hx4f/how_to_c...
Metric money was a similar issue in the 60s. People still thought in shillings for decades. I read that historically (especially in Britain) entirely different counting systems were used simultaneously. Shepherds had their sheep counting numbers, sailors had a different one.
Dialects ran deep, not long ago.
Incidentally, it's lucky that metric never became known as "The French System."
At least metric fasteners are becoming common enough that I can use almost 100% in my designs.
The only "in your face" use of imperial is speed limits. Maybe one day that will get fixed.
Edit, hey this actually works out quite well, 1 for walking speed in parking lots and 15 round town.
Though I do think going the other way might be better. 3000 down the highway.
They use traditional Burmese units. Non-metric doesn't equal imperial/US customary.
Btw before the coup Myanmar seemed to be on a path to finally convert to metric system, but now I think they have bigger issues to worry about.
