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 62.22 Millimeters of Mercury?


1 Millimeters of Mercury = 0.133322387415 kilopascals

62.22 Millimeters of Mercury = Y kilopascals

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

Y equals 62.22 times 0.133322387415 over 1

(i.e.) Y = 62.22 * 0.133322387415 / 1 = 8.2953189449613 kilopascals

Answer is: 8.2953189449613 kilopascals are equivalent to 62.22 Millimeters of Mercury.
