**Definitions:**

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

**Megapascal** (abbreviations: **Mpa, or MN/m2, or N/mm2**): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one meganewton per square meter or one newton per square millimeter. It is named after the French polymath Blaise Pascal.

## How to Convert Atmospheres to Megapascals

*Example: How many megapascals are equivalent to 35.9 Atmospheres?*

As;

1 Atmospheres = 0.1013 megapascals

35.9 Atmospheres = Y megapascals

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

Y equals 35.9 times 0.1013 over 1

(i.e.) Y = 35.9 * 0.1013 / 1 = 3.63667 megapascals

Answer is: 3.63667 megapascals are equivalent to 35.9 Atmospheres.
