A pressure unit converter converts between all common pressure measurement units instantly. Enter a value in any unit — all other units update simultaneously.
How to Convert Pressure Units
Enter any pressure value in any unit field — all other units update automatically. This bidirectional converter handles PSI, bar, kPa, MPa, atm, mmHg, inHg, Pa, and torr.
Common Pressure Applications
Car tire pressure: typically 30-35 PSI (207-241 kPa). Blood pressure: measured in mmHg (120/80 mmHg = normal). Atmospheric pressure: 1 atm = 101.325 kPa = 14.696 PSI. HVAC system pressure: typically measured in PSI or kPa.
FAQ
How do I convert PSI to bar?
1 PSI = 0.0689476 bar. Multiply PSI by 0.068948 to get bar. For quick estimates: 15 PSI ≈ 1 bar, 30 PSI ≈ 2 bar, 100 PSI ≈ 6.9 bar.
What is the difference between kPa and PSI?
Both are pressure units. 1 PSI = 6.89476 kPa. Standard atmospheric pressure = 101.325 kPa = 14.696 PSI. Car tire pressure of 32 PSI = about 220 kPa.
What is atmospheric pressure in different units?
Standard atmospheric pressure = 1 atm = 101.325 kPa = 1.01325 bar = 14.696 PSI = 760 mmHg = 29.92 inHg.
