To convert bar to PSI, multiply by 14.5038.
1 bar = 14.503774 psi
Convert 2.4 bar (tire pressure) to PSI: 2.4 × 14.5038 = 34.81 PSI
Convert 200 bar (scuba tank) to PSI: 200 × 14.5038 = 2,900.76 PSI
To convert PSI to bar, divide by 14.5038, or multiply by 0.0689476.
\u2022 1 bar (14.5 psi) is roughly equal to atmospheric pressure at sea level.
\u2022 2.4 bar (34.8 psi) is standard car tire pressure in many vehicles.
\u2022 8 bar (116 psi) is a typical air compressor operating pressure.
\u2022 200 bar (2,901 psi) is the pressure in a full scuba diving tank.
Bar to PSI conversion is needed when working with pressure specifications across international borders. Equipment manufactured in Europe typically uses bar, while American specifications use PSI.
If your European car’s door placard recommends 2.4 bar for front tires and 2.2 bar for rear tires, you need 34.8 PSI and 31.9 PSI respectively at a US gas station air pump. Many tire pressure monitoring systems (TPMS) can be set to display in either unit.
Espresso machines operate at 9 bar (130.5 PSI). This specific pressure is critical for proper extraction. Home espresso machine specifications are often in bar, while American discussions may reference PSI. Understanding both helps evaluate machine quality.
European pressure washers are rated in bar, while American models use PSI. A light-duty washer runs at about 70-100 bar (1,015-1,450 PSI). Heavy-duty commercial units reach 200+ bar (2,900+ PSI). Comparing models internationally requires this conversion.
1 bar equals approximately 14.5038 PSI.
Multiply the bar value by 14.5038. For example, 2.5 bar × 14.5038 = 36.26 PSI.
2.2 bar is approximately 31.9 PSI.
Bar is a metric unit of pressure. 1 bar is approximately equal to atmospheric pressure at sea level (1 atm = 1.01325 bar). It’s widely used in Europe for tire pressure, industrial applications, and weather.
