In next fields, kindly type your value in the text box under title [ From: ] to convert from megapascal to Atmosphere (mpa to atm). As you type your value, the answer will be automatically calculated and displayed in the text box under title [ To: ].

**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 42.21 megapascals?*

As;

1 megapascals = 9.8717 Atmospheres

42.21 megapascals = Y Atmospheres

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

Y equals 42.21 times 9.8717 over 1

(i.e.) Y = 42.21 * 9.8717 / 1 = 416.684457 Atmospheres

Answer is: 416.684457 Atmospheres are equivalent to 42.21 megapascals.
