Millimeter of mercury to hectopascal formula

To convert millimeter of mercury to hectopascal, multiply by 1.333224.

1 mmHg = 1.333224 hPa
Example: 1 millimeter of mercury = 1.333224 hectopascal

Common pressure conversion mistakes

  • 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.
