Millimeters of Mercury to Pascals Converter

To convert a measurement in millimeters of mercury to pascals, multiply the value by 133.322387. The conversion factor comes from the relationship between both units and the pascal.

For example, to convert 5 mmHg to pascals: 5 × 133.322387 = 666.611937 Pa.

A millimeter of mercury (mmHg) is a unit of pressure equal to the pressure exerted by a one-millimeter-high column of mercury, about 133.32 pascals. Derived from early mercury barometers, the mmHg is nearly identical to the torr. It remains the standard unit for blood pressure and other physiological measurements in medicine worldwide.

Common uses of millimeters of mercury include: Blood pressure readings (systolic/diastolic); Intraocular and intracranial pressure; Barometric pressure in medicine; Vacuum and gas-pressure measurement.

A pascal is the SI derived unit of pressure, equal to one newton of force per square meter (1 N/m²). Named after the French mathematician and physicist Blaise Pascal, the unit was adopted by the International System of Units in 1971. It is a small unit, so everyday pressures are usually expressed in kilopascals or bars.

Common uses of pascals include: Scientific and engineering stress calculations; Meteorological reporting (via hectopascals); Material strength and tensile testing; Fluid mechanics and aerodynamics.

Here are some common values converted:

1 mmHg = 133.322387 Pa 5 mmHg = 666.611937 Pa 10 mmHg = 1,333.2239 Pa 50 mmHg = 6,666.1194 Pa 100 mmHg = 13,332.2387 Pa
