About this calculator

This calculator converts pressure from pounds per square inch (PSI) to bar using the exact conversion factor of 1 bar = 14.5038 PSI — useful for reading imperial pressure gauges or imported equipment specifications against metric compressor and pipeline data.

Formula

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

Worked Example

Given: An imported gauge reads 100 PSI.

Result: 100 ÷ 14.5038 = 6.89 bar.

How to Use

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

Important Assumptions

  • Does not convert between gauge and absolute pressure — only between units.

Common Mistakes

  • Rounding 14.5038 to 14.5, which introduces small errors on high-pressure systems.

Frequently Asked Questions

Why is 1 bar equal to 14.5038 PSI specifically?

Because 1 bar = 100,000 pascals exactly, and 1 PSI = 6,894.76 pascals; dividing gives the 14.5038 conversion factor.
