Frequently asked questions

What is standard atmospheric pressure?

1 atm = 101,325 Pa = 1013.25 mbar = 14.696 psi = 760 mmHg.

What unit do tyre pressures use?

UK/US: psi. Continental Europe: bar. 1 bar ≈ 14.5 psi.

Is mmHg the same as torr?

Very nearly. 1 torr = 1/760 atm = 133.322 Pa. 1 mmHg = 133.322 Pa. They differ by less than 0.002%.
