Frequently Asked Questions
How do I convert PSI to bar?
Divide PSI by 14.5038 to get bar. For example, 30 PSI = 2.07 bar.
What is standard atmospheric pressure?
Standard atmospheric pressure is 1 atm = 101.325 kPa = 14.696 PSI = 1.01325 bar.
What's the difference between PSI and PSIA?
PSI measures gauge pressure (relative to atmosphere), while PSIA measures absolute pressure (relative to vacuum).
What pressure units are used for tires?
US uses PSI, Europe uses bar or kPa. Typical tire pressure is 30-35 PSI (2.0-2.4 bar).
