Conversion Definitions
The following is a list of definitions relating to conversions between atmospheres and pascals.
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 0.00000987 atmospheres in a pascal.
What is a pascal (Pa)?
A pascal is a unit of Pressure in the International System of Units (SI). The symbol for pascal is Pa. There are 101,325 pascals 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 Pa is:
Pa = atm x 101,325
Conversion Example
Next, let's look at an example showing the work and calculations that are involved in converting from atmospheres to pascals (atm to Pa).
Atmosphere to Pascal Conversion Example
Task: Convert 4 atmospheres to pascals (show work) Formula: atm x 101,325 = Pa Calculations: 4 atm x 101,325 = 405,300 Pa Result: 4 atm is equal to 405,300 Pa
