Formula to convert hectopascal to millimeter of mercury

To convert hectopascal to millimeter of mercury, multiply by 0.750062.

1 hPa = 0.750062 mmHg
Example: 1 hectopascal = 0.750062 millimeter of mercury

Common mistakes in pressure conversion

  • 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.
