**Definitions:**

**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.

**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.

## How to Convert Millimeters Of Mercury to Megapascals

*Example: How many megapascals are equivalent to 4.61 Millimeters of Mercury?*

As;

1 Millimeters of Mercury = 0.000133 megapascals

4.61 Millimeters of Mercury = Y megapascals

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

Y equals 4.61 times 0.000133 over 1

(i.e.) Y = 4.61 * 0.000133 / 1 = 0.00061313 megapascals

Answer is: 0.00061313 megapascals are equivalent to 4.61 Millimeters of Mercury.
