**Definitions:**

**Pascal** (abbreviations: **Pa, or N/m2**): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one newton per square meter. 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 Pascals to Millimeters Of Mercury

*Example: How many Millimeters of Mercury are equivalent to 64.05 pascals?*

As;

1 pascals = 0.0075006157584566 Millimeters of Mercury

64.05 pascals = Y Millimeters of Mercury

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

Y equals 64.05 times 0.0075006157584566 over 1

(i.e.) Y = 64.05 * 0.0075006157584566 / 1 = 0.48041443932914 Millimeters of Mercury

Answer is: 0.48041443932914 Millimeters of Mercury are equivalent to 64.05 pascals.
