**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.

**Tonne Per Meter Cube** (abbreviations: **t/m2, or tpm2**): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength interms of tonne per meter cube.

## How to Convert Millimeters Of Mercury to Tonnes Per Meters Cube

*Example: How many tonnes per meters cube are equivalent to 4.42 Millimeters of Mercury?*

As;

1 Millimeters of Mercury = 0.0133322387415 tonnes per meters cube

4.42 Millimeters of Mercury = Y tonnes per meters cube

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

Y equals 4.42 times 0.0133322387415 over 1

(i.e.) Y = 4.42 * 0.0133322387415 / 1 = 0.05892849523743 tonnes per meters cube

Answer is: 0.05892849523743 tonnes per meters cube are equivalent to 4.42 Millimeters of Mercury.
