About the units

Millimeter of mercury (mmHg)

The conventional mmHg is 133.322387415 Pa. Blood pressure is measured in mmHg (e.g. 120/80).

Megapascal (MPa)

One million pascals, equal to 1 N/mm². Concrete and steel strengths are given in MPa. One megapascal equals 1,000,000 pascals (Pa).

Frequently asked questions

How many megapascals are in one millimeter of mercury?

There are 0.0001333223874 megapascals in one millimeter of mercury, and this value is exact by definition.

How do I convert millimeters of mercury to megapascals?

Multiply the number of millimeters of mercury by 0.0001333223874. For example, 10 mmHg × 0.0001333223874 = 0.001333223874 MPa.
