Yea, that’s not going happen. I’m amazed we don’t use “cubits” down here based on the arguments used against the metric system


seriously though, I've totally lost my ounces stuff and always find it confusing when folks describe x camping gear in ounces...
And yet, still haven't picked up on bar tire pressure and only understand psi.....
Well if you are going to be all Système international (d'unités), “bar” isn’t the measurement you use. You use Pascals (N/m2).

“Bar” is atmospheric pressure or 14 psi/atmosphere. 100 psi~7 atmosphere or about 7 bar. Of course, that assumes sea level. Up here at around 1600 meters, our “atmospheric pressure” is 80% of that of sea level.

Pascals are harder to use (and wrap your head around) because there are just so many of them. One standard atmosphere (14 psi) is 96,500 pascals. 100 psi is 675,000 pascal. Even if you convert it to kilo pascals (kpa), that 675 kpa which is still hard to think about. Even professionally, few people use pascals.

I had to be a metric interpreter on a VBT Bike and Barge tour I did several years ago. They gave us queue sheets for directions. There wasn’t a map, just a list of directions. The sheets would say “0.1: Turn left” or “1.3: turn right”. Each direction might have a street name but many didn’t. All the ‘Mericans would look at the sheet and say (out loud) “Oh, that’s a tenth of a mile” or “that’s 1.3 miles.” I have to constantly remind them that 0.1 was a tenth of a kilometer or about a city block or, more practically, “Right now!”

I had to interpret from metric to imperial (really just ‘Merican now) for the Dutch guides. They couldn’t wrap their heads around temperature in Fahrenheit (nor could the ‘Mericans think in Celsius). I explained that 20°C is room temperature and body temperature is 37°C.

Luckily we never had to deal with volume or pressure.
