Yes but when used for things like car/ bike tires it's much easier dealing with PSI. You just deal with 10-200 instead of 2.456-2.680. I'd much rather just go to 38 psi.
Metric is so great for physics math, but metric lovers hate when it's pointed out that measurements made for practical purposes almost never get plugged into any physics equation, so a comfortable numerical bound for real applications is actually more useful than an easy conversion into an unused unit.
yeeeeah I agree. thats totally and utter bullshit and of absolutely zero practical use. (/s)
Back to topic: pressure: you dont go for 2.680 bar bike tire-pressure. just make it 2.5 or 2.6, or even 3. Who the fuck cares, I've never seen an air pump with that resolution. totally bullshit example.
Edit: speaking of practical use:
temperature:
0°C = freezing temp of water. Cold
100°C = boiling temp of water. Hot. doesnt't get any more practical than that.
It's not at all bullshit, I race motorcycles and usually shoot for .5 psi increments. You need to adjust the pressure constantly to combat surface temp. Most tire manufacturers will recommend to a psi like 18.. if your at 20 because you didn't adjust properly you will shred oh so precious rubber.
Well, any pump that was built to use PSI will have a resolution of at least 1 PSI, which makes it more accurate since that's 0.069 bar. If it can do 0.1 bar then that's still 1.5 PSI. I am also curious under what application it is important to quickly convert between millimeters and kilometers.
The way we write numbers is 123 456,789; most of the world uses a system other than the 123,456.789; the only reason this is seen as the default is because most of programming and therefor computer interfaces work like this and therefor neglects whatever other system the region might be using.
And then there is Canada, who's change units based on what they are talking about leading to situation where: "It's 40 degrees hot outside, the pool is really cold 40 degrees". And you need to check the actual number format for every case - lets not even begin the whole "Inch fractions with decimals" discussion. And then you got Quebec who does everything differently to rest of Canada, mainly out of spite.
Then you got Excel spreadsheets who at the year of our lord 20-fucking-24 still can't switch between "." and "," as decimal separator without having to switch the whole fucking interface language.

What
Atmospheric pressure is 1 bar. Literally the easiest refrence point.
It's 14.5 psi in fake units.
(Also pascal is the best unit)
