About this converter
Atmospheric pressure
Standard sea-level pressure: 1 atm = 101,325 Pa = 1013.25 mbar = 14.696 PSI = 29.92 inHg = 760 mmHg. Weather forecasts often use mbar (Europe) or inHg (US).
Tire pressure
US car tires are usually 30-35 PSI. That equals about 207-241 kPa or 2.1-2.4 bar (the common European/Asian label).
Blood pressure
BP is reported in mmHg (also called "torr"). Normal: under 120/80 mmHg systolic/diastolic. 1 mmHg ≈ 133.32 Pa.
