Conversion Definitions
The following is a list of definitions relating to conversions between atmospheres and kilopascals.
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 0.00986923 atmospheres in a kilopascal.
What is a kilopascal (kPa)?
A kilopascal is a unit of Pressure in the International System of Units (SI). The symbol for kilopascal is kPa. There are 101.325 kilopascals 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 kPa is:
kPa = 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 kilopascals (atm to kPa).
Atmosphere to Kilopascal Conversion Example
Task: Convert 4 atmospheres to kilopascals (show work) Formula: atm x 101.325 = kPa Calculations: 4 atm x 101.325 = 405.3 kPa Result: 4 atm is equal to 405.3 kPa
