I dont know the conversions, cause my life is fully metric by luck of being born in it.
I know that atmospheric pressure is 1 bar (the normal air around us), my car tyres need 2.5 Bar and my bike tyres 4 Bar.
But you seem to be correct, it’s 14.5 lbs/"²
I guess so. We wouldn’t write 5 ms for metres. Plus the pounds weight - pounds force dilemma
ergo
PSI < lbs/"² < lb/"² < lbf/"² <<<<<<<<< Bar < Pa
