How it works

All pressures are routed through pascals, the SI base unit, using standard definitions such as 1 atm = 101,325 Pa.

Frequently asked questions

What pressure are car tyres?

Most passenger cars run 30-35 psi, which is roughly 2.1-2.4 bar.

Is torr the same as mmHg?

They differ by less than one part per seven million, so for practical work they are interchangeable.
