Bar to PSI Converter
Convert pressure from bar to pounds per square inch (psi). One bar equals about 14.5038 psi. This is handy for tyre pressures, dive cylinders and any spec given in bar that you need in psi. Enter a value in bar to get the equivalent in psi.
Formula
psi = bar × 14.5038
- 1 bar = 100,000 Pa, and 1 psi = 6,894.76 Pa, so 1 bar = 14.5038 psi.
- Tyre pressures are a common use: 2.2 bar is roughly 32 psi.
- To convert psi back to bar, divide by 14.5038 (or multiply by 0.0689476).
- Bar and psi both measure pressure relative to the same zero, so the conversion is a simple multiplication.
Convert 2 bar to psi
Inputs
- Pressure: 2 bar
2 bar × 14.5038 = 29.01 psi. A typical car tyre at 2.2 bar would be about 31.9 psi.
