**Definitions:**

**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.

**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 Tonnes Per Meters Cube to Millimeters Of Mercury

*Example: How many Millimeters of Mercury are equivalent to 78.84 tonnes per meters cube?*

As;

1 tonnes per meters cube = 75.002 Millimeters of Mercury

78.84 tonnes per meters cube = Y Millimeters of Mercury

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

Y equals 78.84 times 75.002 over 1

(i.e.) Y = 78.84 * 75.002 / 1 = 5913.15768 Millimeters of Mercury

Answer is: 5913.15768 Millimeters of Mercury are equivalent to 78.84 tonnes per meters cube.
