**Definitions:**

**Kilopascal** (abbreviations: **kPa, or kN/m2**): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one kilonewton 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 Kilopascals to Millimeters Of Mercury

*Example: How many Millimeters of Mercury are equivalent to 31.68 kilopascals?*

As;

1 kilopascals = 7.5002 Millimeters of Mercury

31.68 kilopascals = Y Millimeters of Mercury

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

Y equals 31.68 times 7.5002 over 1

(i.e.) Y = 31.68 * 7.5002 / 1 = 237.606336 Millimeters of Mercury

Answer is: 237.606336 Millimeters of Mercury are equivalent to 31.68 kilopascals.
