Conversion
1 Bar = 14.503774 Pounds per square inch (psi)

Convert pressure between bar, psi, pascals, atmospheres, and more, whether you are checking tire pressure, a weather reading, or an industrial gauge. Choose two units and enter a value.

How this is calculated

Values route through the pascal, the SI unit of pressure. One bar is 100000 pascals, one standard atmosphere is 101325 pascals, and one psi is a pound of force per square inch, which equals about 6894.76 pascals. Millimeters of mercury use the convention that one atmosphere is 760 mmHg.

How to use

  1. Enter the pressure value.
  2. Choose the unit you have and the unit you want.
  3. Read the result, or press Swap to reverse.

Examples

  • Bar to psi: 1 bar = 14.503774 psi
  • Atmosphere to psi: 1 atm = 14.695949 psi
  • psi to kilopascals: 32 psi = 220.632233 kPa

FAQ

How many psi is one bar?
One bar is about 14.5 psi. Car tire pressures are often quoted in both.
Is mmHg the same as torr?
They are equal here. Both use the convention that one atmosphere is exactly 760 units, so 1 mmHg equals 1 torr.
