Conversion Definitions
The following is a list of definitions relating to conversions between atmospheres and megapascals.
What is an atmosphere (atm)?
An atmosphere (or standard atmosphere) is a non-SI unit of Pressure. The symbol for atmosphere is atm. There are 9.8692 atmospheres in a megapascal.
What is a megapascal (MPa)?
A megapascal is a unit of Pressure in the International System of Units (SI). The symbol for megapascal is MPa. There are 0.101325 megapascals in an atmosphere.
Conversion Formula
Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.
The formula to convert from atm to MPa is:
MPa = atm x 0.101325
Conversion Example
Next, let's look at an example showing the work and calculations that are involved in converting from atmospheres to megapascals (atm to MPa).
Atmosphere to Megapascal Conversion Example
Task: Convert 350 atmospheres to megapascals (show work) Formula: atm x 0.101325 = MPa Calculations: 350 atm x 0.101325 = 35.46375 MPa Result: 350 atm is equal to 35.46375 MPa
