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 mmHg are in 1 kPa?

1 kPa equals 7.5 mmHg.

How many mmHg are in 2 kPa?

2 kPa equal 15 mmHg.

How do I convert kPa to mmHg?

Multiply the pressure in kPa by 7.5 to get mmHg.

Is the kPa-to-mmHg conversion exact?

Yes. Pressure conversions rest on fixed factors; the values here are only rounded to two decimal places.

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.
