Pressure Unit Conversion

Convert between pressure units used in automotive, weather, engineering, and science applications.

1 bar = 14.504 psi | 1 atm = 101.325 kPa

1 psi = 6.895 kPa | Standard tire pressure: 30-35 psi = 2.1-2.4 bar

How do I convert bar to PSI?

Multiply bar by 14.504. Example: 2 bar = 29 PSI.

What is standard atmospheric pressure?

1 atm = 101,325 Pa = 1.01325 bar = 14.696 PSI = 760 mmHg.
