Frequently Asked Questions

It supports pascal (Pa), kilopascal (kPa), megapascal (MPa), bar, millibar, psi, atm, and mmHg (torr).

1 standard atmosphere (atm) equals approximately 14.696 psi.

1 bar equals approximately 14.504 psi. Bar is used in Europe and scientific contexts; psi is common in the US and UK.

Standard atmospheric pressure at sea level is 101,325 Pa (1 atm), 1.01325 bar, or 14.696 psi.

Car tyre pressure is typically 30-35 psi (2.0-2.4 bar). Check your vehicle's manual for the recommended pressure.

Blood pressure is measured in mmHg (millimetres of mercury). Normal blood pressure is around 120/80 mmHg.

At the deepest point of the ocean (Mariana Trench, ~11 km), pressure is approximately 1,100 bar or 16,000 psi.
