Common pressure conversion mistakes

  • Tire pressure is quoted in bar in Europe and psi in the US: 1 bar is about 14.5 psi. The recommended 2.5 bar equals about 36 psi, inflating to '25 psi' on the assumption they match leaves the tire dangerously underinflated. Multiply bar by 14.5 to get psi.
  • Blood pressure uses mmHg (120/80) and weather reports use hPa (around 1,013), different units that must not be mixed: 760 mmHg = 1,013.25 hPa. One mmHg is about 1.33 hPa.
  • Hectopascals and millibars are exactly the same size: 1 hPa = 1 mbar. A chart showing 1,013 mbar and one showing 1,013 hPa agree perfectly, no conversion needed. Meteorology simply renamed the unit.
