Convert between PSI, bar, Pascal, kilopascal, and atmospheres.

Frequently asked questions

How do you convert PSI to bar?

Divide the PSI value by 14.504, or multiply by 0.06895. For example, 30 PSI is approximately 2.07 bar. Many tyre pressure gauges show both units.

What is standard atmospheric pressure?

Standard atmospheric pressure at sea level is 1 atm, which equals 101,325 Pa, 101.325 kPa, 1.01325 bar, or 14.696 PSI.

What is the difference between bar and PSI?

Bar is a metric unit of pressure equal to 100,000 Pascals. PSI (pounds per square inch) is an imperial unit. One bar equals approximately 14.504 PSI. Bar is more common in Europe, PSI in the US.
