About this calculator

A general-purpose bar-to-PSI converter for any engineering context — hydraulic systems, tyre pressure, boiler ratings, pump discharge — not limited to compressed air. Uses the exact factor of 1 bar = 14.5038 PSI.

Formula

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

Worked Example

Given: A hydraulic system is rated at 1 bar minimum.

Result: 1 × 14.5038 = 14.5 PSI.

How to Use

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

Important Assumptions

  • Unit conversion only; does not distinguish gauge from absolute pressure.

Common Mistakes

  • Applying this to a value already in kPa or MPa without converting to bar first.

Frequently Asked Questions

Is this different from the compressor Bar to PSI converter?

The formula and result are identical — this version is listed under general unit converters for engineering uses beyond compressed air, such as hydraulics or tyre pressure.
