About these units
Bars (bar): One bar is exactly 100,000 pascals, close to atmospheric pressure at sea level. Tyre and gauge pressures in Europe and Asia are often in bar.
PSI (psi): Pounds per square inch (psi) is used for tyre pressure, compressors and hydraulics in the US.
Frequently asked questions
How many PSI are in 1 bar?
1 bar equals 14.50377377 PSI.
How do I convert bar to psi?
Multiply the value in bars by 14.50377377. For example, 5 bar × 14.50377377 = 72.51886887 psi.
How do I convert PSI back to bars?
Multiply by 0.06894757293 (or divide by 14.50377377). 1 psi = 0.06894757293 bar.
What is a bar?
One bar is exactly 100,000 pascals, close to atmospheric pressure at sea level. Tyre and gauge pressures in Europe and Asia are often in bar.
