PSI to Bar Converter (psi to bar)
PSI (pounds per square inch) is the common pressure unit in the US, while bar is used across Europe and Asia. One bar equals 14.5038 psi, so divide psi by 14.5038 to get bar — the conversion used for tyre, compressor and hydraulic pressures.

1 psi = 0.06894757293 bar
Calculation working
- Result = input × source factor ÷ target factor
- 1 × 6,894.75729316836 ÷ 100,000 = 0.0689475729316836 bar
- Factors refer to the same base quantity. Rounding is applied to the display, not intermediate calculations.
Display: 10 significant digits. More digits do not make the original measurement more accurate.

Using this pressure converter
Read gauge labels and compare pressure specifications for tyres, pumps, compressors and hydraulic equipment.
Changing units preserves the pressure reference. A gauge-pressure input remains gauge pressure; an absolute-pressure input remains absolute pressure.
Check before using the result
- Unit conversion alone cannot turn gauge pressure into absolute pressure. That requires the applicable atmospheric-pressure offset.
- A unit conversion does not establish safe operating pressure. Check the manufacturer's rating and the same operating/reference conditions.
Definitions and method: NIST: unit conversion factors and rounding. Calculations use double-precision arithmetic; the display precision can be adjusted above.
