Pressure Converter (bar, psi, Pa, atm)

Convert pressure between pascals, kPa, bar, millibar, psi, atmospheres, mmHg and inHg.

How many psi is 1 bar?

One bar equals 100,000 pascals, about 14.504 psi and roughly the air pressure at sea level (1 atm = 1.01325 bar).

Typical uses: tyre pressure (psi or bar), weather (hPa), blood pressure (mmHg), engineering (MPa) and scuba diving (bar).

What is a normal car tyre pressure?

Usually 30–35 psi (about 2.1–2.4 bar); check the label in your car door.

Is hPa the same as mbar?

Yes, 1 hectopascal equals 1 millibar.

Is psi gauge or absolute?

Conversion factors are the same; tyre gauges show pressure above atmospheric (psig).
