**Definitions:**

**Megapascal** (abbreviations: **Mpa, or MN/m2, or N/mm2**): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one meganewton per square meter or one newton per square millimeter. It is named after the French polymath Blaise Pascal.

**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 Megapascals to Tonnes Per Meters Cube

*Example: How many tonnes per meters cube are equivalent to 79.18 megapascals?*

As;

1 megapascals = 100 tonnes per meters cube

79.18 megapascals = Y tonnes per meters cube

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

Y equals 79.18 times 100 over 1

(i.e.) Y = 79.18 * 100 / 1 = 7918 tonnes per meters cube

Answer is: 7918 tonnes per meters cube are equivalent to 79.18 megapascals.
