**Definitions:**

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

**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 Atmospheres to Tonnes Per Meters Cube

*Example: How many tonnes per meters cube are equivalent to 64.3 Atmospheres?*

As;

1 Atmospheres = 10.1325 tonnes per meters cube

64.3 Atmospheres = Y tonnes per meters cube

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

Y equals 64.3 times 10.1325 over 1

(i.e.) Y = 64.3 * 10.1325 / 1 = 651.51975 tonnes per meters cube

Answer is: 651.51975 tonnes per meters cube are equivalent to 64.3 Atmospheres.
