Comment on About to turn the car to a flying car
Thorry84@feddit.nl 1 day agoAs far as I know hPa is the preferred unit for air pressure and is used a lot. Usually referring to the air pressure of the atmosphere.
Also hectometer is used a lot when talking about land measurements. And we don’t mostly keep to mm and m, in my experience cm is the most used and most useful measurement for every day objects.
All of the different prefixes are valid and are used. It just depends on what context, which one is the most useful. No reason to stick to the 10^3 units, just use them all.

I should clarify, this is my personal preference, for ease of conversion. I wish we stuck to consistent intervals. They’re all valid, just that I find it very lovely that in industrial/construction we don’t use cm (in Australia)
But there are so many various pressure units in use, which is a slight inconvenience. Pa, Bar, atm, cm-water, are the ones I’ve come across in actual use so far. (Metric engineering context, RIP US engineers)
Makes it necessary for me to use a calculator to make sure I’m not messing something up. kPa to mbar: okay *bar/(100 kPa) * 1000 mbar/bar (which I’m now noticing is hPa)
So in addition to my preference for consistent prefix intervals, let’s also stop using Bar, cm-water, and anything else that’s not Pa. That’d be nice ☺️
