About this calculator

This calculator converts pressure from bar to pounds per square inch (PSI) using the exact conversion factor of 1 bar = 14.5038 PSI. It's commonly used when comparing compressor, gauge or pipe fitting specifications between metric and imperial pressure units.

Formula

PSI = bar × 14.5038
  • barPressure — bar
  • PSIPressure — pounds per square inch

Worked Example

Given: A compressor is set to discharge at 7 bar.

Result: 7 × 14.5038 = 101.5 PSI.

How to Use

  1. Enter the pressure value in bar.
  2. Click Calculate to see the equivalent value in PSI.

Important Assumptions

  • This is a gauge-to-gauge or absolute-to-absolute conversion — it does not change whether the value is gauge or absolute pressure, only the unit.

Common Mistakes

  • Confusing gauge pressure (barg/psig) with absolute pressure (bara/psia) — always check which your source value uses.

Frequently Asked Questions

Is this gauge or absolute pressure?

This converts whatever unit type you enter — if you enter barg, you get psig; if bara, you get psia. The numeric conversion factor is the same either way.
