Bar to PSI Converter (bar to psi)
Bar converts to psi by multiplying by 14.5038. A typical car tyre at 2.2 bar is about 32 psi, and a workshop compressor at 8 bar is roughly 116 psi.

1 bar = 14.50377377 psi
Calculation working
- Result = input × source factor ÷ target factor
- 1 × 100,000 ÷ 6,894.75729316836 = 14.5037737730209 psi
- 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.
