**Definitions:**

**Megapascal** (abbreviations: **Mpa, or MN/m2, or N/mm2**): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one meganewton per square meter or one newton per square millimeter. It is named after the French polymath Blaise Pascal.

**Millimeter Of Mercury** (abbreviations: **mm Hg, or mmHg**): is a manometric unit of pressure, equal to 133.322387415 pascals. It is the extra pressure generated by a column of mercury of one millimeter high.

## How to Convert Megapascals to Millimeters Of Mercury

*Example: How many Millimeters of Mercury are equivalent to 85.45 megapascals?*

As;

1 megapascals = 7500.2 Millimeters of Mercury

85.45 megapascals = Y Millimeters of Mercury

Assuming Y is the answer, and by criss-cross principle;

Y equals 85.45 times 7500.2 over 1

(i.e.) Y = 85.45 * 7500.2 / 1 = 640892.09 Millimeters of Mercury

Answer is: 640892.09 Millimeters of Mercury are equivalent to 85.45 megapascals.
