psi, bar, and pascal — the key pressure units

The pascal (Pa) is the SI unit of pressure; the kilopascal (kPa) and megapascal (MPa) are its multiples. The bar equals exactly 100,000 Pa and is close to air pressure — but beware: 1 bar is not equal to 1 atmosphere (atm), because 1 atm is 101,325 Pa (about 1.3% more). psi (pound-force per square inch) is the US unit for tire and pneumatic pressures, and mmHg (torr) is used for blood pressure and vacuum work.

Watch out for gauge vs. absolute pressure: psi values are usually gauge (psig) — that is, above ambient. Tire pressures are quoted this way. For more unit pairs, use our pressure conversion hub.

Frequently asked questions

How many bar are in 1 psi?

1 psi equals 0.0689 bar.

How many bar are in 2 psi?

2 psi equal 0.138 bar.

How do I convert psi to bar?

Divide the pressure in psi by 14.5 to get bar.

Is psi gauge or absolute pressure?

In practice, psi is usually gauge pressure (psig) — the pressure above ambient air. Tire and pneumatic pressures are quoted this way. Absolute pressure (psia) is measured from a vacuum and is about 14.7 psi (1 atm) higher.

What are these pressure units used for?

Pascals (Pa), kilopascals (kPa), and megapascals (MPa) are the SI units of pressure. The bar and millibar (mbar) are used in meteorology and engineering, psi mainly for tires and pneumatics (US), the atmosphere (atm) as a reference pressure, and mmHg (torr) for blood pressure and vacuum work.
