Hectopascals to Millimeters of mercury converter

To convert hectopascals to millimeters of mercury, enter the value in the first field. The result in millimeters of mercury is calculated automatically using the exact conversion factor.

1 hPa ≈ 0.750061575846 mmHg
1 mmHg = 1.33322387415 hPa

Formula: mmHg ≈ hPa × 0.750061575846
hPa = mmHg × 1.33322387415

Definitions: 1 hPa = 100 Pa; 1 mmHg = 133.322387415 Pa

The hectopascal (hPa) equals 100 pascals and is exactly the same as one millibar. It is the unit weather services use for atmospheric pressure, with average sea-level pressure around 1013 hPa.

The millimeter of mercury (mmHg) is the pressure at the base of a one-millimeter column of mercury. It is the unit of blood pressure in medicine, for example 120/80 mmHg, and is also used for some barometric and vacuum readings.
