**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.

**Atmosphere** (abbreviation: **atm**): is a unit of standard pressure, equal to 101325 Pa, or 1.01325 bar.

## How to Convert Tonnes Per Meters Cube to Atmospheres

*Example: How many Atmospheres are equivalent to 70.26 tonnes per meters cube?*

As;

1 tonnes per meters cube = 0.0987 Atmospheres

70.26 tonnes per meters cube = Y Atmospheres

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

Y equals 70.26 times 0.0987 over 1

(i.e.) Y = 70.26 * 0.0987 / 1 = 6.934662 Atmospheres

Answer is: 6.934662 Atmospheres are equivalent to 70.26 tonnes per meters cube.
