PSI to bar converter

Convert PSI to bar, both ways.

Type a pressure in pounds per square inch and read the exact value in bar, or type bar to convert back. The result updates live, with kilopascals, atmospheres and real-world tire context and a one-click copy.

What this means

    Common pressures in bar

    bar Each bar shows the bar equivalent of a common pressure, from atmospheric pressure at 14.7 psi to an espresso machine pump at 130 psi. Every height is the psi value multiplied by 0.0689476.

    How the conversion works

    Conversion Factor

    1 PSI equals 0.0689 bar. 1 bar = 14.504 PSI. Bar is metric (very close to 1 atmosphere of pressure). PSI is US imperial. Multiply PSI by 0.0689 to get bar.

    Tire Pressure Conversion

    European tire pressure is given in bar; US in PSI. A typical car tire at 32 PSI = 2.21 bar. Mountain bike around 30 PSI = 2.07 bar. Road bike 100+ PSI = 6.9+ bar.

    Reference Values

    1 PSI = 0.069 bar. 14.5 PSI = 1 bar (≈ 1 atmosphere). 32 PSI = 2.21 bar (car tire). 100 PSI = 6.89 bar (road bike). 200 PSI = 13.79 bar.

    Common questions

    32 PSI tire pressure in bar?

    32 PSI = 2.21 bar, typical car tire pressure.

    Is 1 bar = 1 atmosphere?

    Very close. 1 bar = 0.987 atm. The 1.3% difference rarely matters in everyday use.

    Why use bar instead of PSI?

    Bar is metric and close to atmospheric pressure for intuitive readings. PSI is conventional in US engineering and tire labels.

    All conversion runs in your browser. Nothing is uploaded. 1 psi is defined as one pound-force per square inch, which is 0.0689476 bar, so these results are precise, not approximate. Standard atmosphere (1.01325 bar) and bar differ slightly.
