**Definitions:**

**Bar** (abbreviation: **bar**): is a metric (still not approved by the International System of Units, SI) unit of pressure. It is exactly equal to 100,000 Pa and slightly lower than the current average atmospheric pressure on Earth, at sea level.

**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 Bars to Tonnes Per Meters Cube

*Example: How many tonnes per meters cube are equivalent to 11.21 Bars?*

As;

1 Bars = 10 tonnes per meters cube

11.21 Bars = Y tonnes per meters cube

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

Y equals 11.21 times 10 over 1

(i.e.) Y = 11.21 * 10 / 1 = 112.1 tonnes per meters cube

Answer is: 112.1 tonnes per meters cube are equivalent to 11.21 Bars.
