Millimeters of mercury to Pascals converter

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

1 mmHg = 133.322387415 Pa
1 Pa ≈ 0.00750061575846 mmHg

Formula: Pa = mmHg × 133.322387415
mmHg ≈ Pa × 0.00750061575846

Definitions: 1 mmHg = 133.322387415 Pa

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.

The pascal (Pa) is the SI unit of pressure, one newton per square meter. It is a very small unit, so everyday pressures are usually given in kilopascals or hectopascals, but the pascal is the base of physics, acoustics and engineering formulas.
