How to Convert mmHg to Pascal

Formula

Pascal = mmHg × 133.322

Worked Example

Example: 5 mmHg = 5 × 133.322 = 666.61 Pascal

To convert mmHg to Pascal, multiply the mmHg value by 133.322. This factor is derived from the ratio between the two units.

About These Units

mmHg

Millimeters of Mercury

Millimeters of mercury (also called Torr) is a unit of pressure based on the height of a mercury column. It is the standard unit for measuring blood pressure (e.g., 120/80 mmHg) and is also used in vacuum technology.

History

The mmHg unit originates from Torricelli's barometer invention in 1643. Standard atmospheric pressure supports a mercury column of exactly 760 mm. The unit is named 'Torr' in honor of Torricelli. It remains the universal standard for blood pressure measurement.

Pascal

The pascal is the SI unit of pressure defined as one newton per square meter. It is used in science, engineering, and meteorology. Since one pascal is a very small pressure, kilopascals (kPa) and megapascals (MPa) are more commonly used in practice.

History

The pascal is named after French mathematician and physicist Blaise Pascal, who made important contributions to the study of fluid mechanics and pressure in the 17th century. It was adopted as the SI unit of pressure in 1971.

How these conversions work

Each category converts first through a base unit, then into the destination unit. That keeps the math consistent across metric and imperial systems and makes it easier to explain how results are generated.

When to double-check

Use these tools for planning, study, and everyday reference. For regulated, medical, engineering, or procurement work, confirm requirements against the official standard or specification you are working from.
