**Definitions:**

**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.

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

## How to Convert Megapascals to Atmospheres

*Example: How many Atmospheres are equivalent to 44.4 megapascals?*

As;

1 megapascals = 9.8717 Atmospheres

44.4 megapascals = Y Atmospheres

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

Y equals 44.4 times 9.8717 over 1

(i.e.) Y = 44.4 * 9.8717 / 1 = 438.30348 Atmospheres

Answer is: 438.30348 Atmospheres are equivalent to 44.4 megapascals.
