**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.

**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.

## How to Convert Tonnes Per Meters Cube to Megapascals

*Example: How many megapascals are equivalent to 28.56 tonnes per meters cube?*

As;

1 tonnes per meters cube = 0.01 megapascals

28.56 tonnes per meters cube = Y megapascals

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

Y equals 28.56 times 0.01 over 1

(i.e.) Y = 28.56 * 0.01 / 1 = 0.2856 megapascals

Answer is: 0.2856 megapascals are equivalent to 28.56 tonnes per meters cube.
