Sorry for drifting off-topic-

But I grew up at a time when the US was planning to go "dual measurement", so we learned all of it in grade school (grades 2-5) and then the rest of America heaved a sigh of relief as the government gave up on metric measurements.
To this day Metric still make so much more sense to me than Imperial measurements.

It really shined through when I was technical scuba diving-

Rather than converting PSI to Cu Ft/min (for breathing rate) and then applying a division of 34' (freshwater) per atmosphere (14.7psi) - ALL for gas consumption at a given depth! There was a simple-

tank pressure in BAR, gas consumption in BAR/min, for depth 10m = 1 Bar = each 10m/1 your surface breathing consumption. All you had to do was divide your surface rate by your depth in 10m increments.

Things like gas absorption/saturation/off-gassing were when things got REALLY hairy in Imperial! Doubly & Trebly so if something went all pear-shaped and your first 3 gas-plans had to be scrapped so you had to do calculations on the fly.
