About the units

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).

Inch of mercury (inHg)

About 3,386.39 Pa. US weather reports and aircraft altimeters use inches of mercury (standard is 29.92 inHg). One inch of mercury equals 3,386.38864 pascals (Pa).

Frequently asked questions

How many inches of mercury are in one megapascal?

There are 295.299833 inches of mercury in one megapascal, and this value is exact by definition.

How do I convert megapascals to inches of mercury?

Multiply the number of megapascals by 295.299833. For example, 10 MPa × 295.299833 = 2,952.99833 inHg.
