There was a point back when, when USSR TV weather people started reading out conditions and forecasts in hecto-pascals. Every time was country-wide FTW moment.
I'm convinced that at least half of the things the Soviet Union did in the 80's were solely to screw with the West. Not out of any real desire to cause issues, just more so to make people go, "huh? Effing weirdos....."
And if you want to add a layer of confusion, try putting an atmospheric pressure reading into your dive computer as a means of checking sensor accuracy. You then need to explain to users who are not at sea level that most local weather sites one uses for reference don’t publish the actual atmospheric pressure, but a “sea level corrected” pressure, i.e. what the actual pressure would be if they were at sea level. That is unless the weather station is catering to aviation, when actual “station pressure” is used.

I use station pressure when shooting, Trying to explain it to people at the range gets me lots of confused looks. It's not difficult to understand, but if you've never been exposed to the differences and their uses, it's like trying to get a house cat to fly a kite.
