**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.

**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.

## How to Convert Millimeters Of Mercury to Kilopascals

*Example: How many kilopascals are equivalent to 4.58 Millimeters of Mercury?*

As;

1 Millimeters of Mercury = 0.133322387415 kilopascals

4.58 Millimeters of Mercury = Y kilopascals

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

Y equals 4.58 times 0.133322387415 over 1

(i.e.) Y = 4.58 * 0.133322387415 / 1 = 0.6106165343607 kilopascals

Answer is: 0.6106165343607 kilopascals are equivalent to 4.58 Millimeters of Mercury.
