**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.

**Pound Per Square Inch** (abbreviations: **psi, or lb/in2**): is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.

## How to Convert Tonnes Per Meters Cube to Pounds Per Square Inches

*Example: How many pounds per square inches are equivalent to 67.04 tonnes per meters cube?*

As;

1 tonnes per meters cube = 1.45038 pounds per square inches

67.04 tonnes per meters cube = Y pounds per square inches

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

Y equals 67.04 times 1.45038 over 1

(i.e.) Y = 67.04 * 1.45038 / 1 = 97.2334752 pounds per square inches

Answer is: 97.2334752 pounds per square inches are equivalent to 67.04 tonnes per meters cube.
