**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.

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

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

*Example: How many kilopounds per square inches are equivalent to 0.3 tonnes per meters cube?*

As;

1 tonnes per meters cube = 0.00145038 kilopounds per square inches

0.3 tonnes per meters cube = Y kilopounds per square inches

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

Y equals 0.3 times 0.00145038 over 1

(i.e.) Y = 0.3 * 0.00145038 / 1 = 0.000435114 kilopounds per square inches

Answer is: 0.000435114 kilopounds per square inches are equivalent to 0.3 tonnes per meters cube.
