Conversion Definitions
The following is a list of definitions relating to conversions between pascals and atmospheres.
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.
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.
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 Pa to atm is:
atm = Pa ÷ 101,325
Conversion Example
Next, let's look at an example showing the work and calculations that are involved in converting from pascals to atmospheres (Pa to atm).
Pascal to Atmosphere Conversion Example
Task: Convert 85,000 pascals to atmospheres (show work) Formula: Pa ÷ 101,325 = atm Calculations: 85,000 Pa ÷ 101,325 = 0.83888478 atm Result: 85,000 Pa is equal to 0.83888478 atm
