How to Convert Kilopascals to Atmospheres
To convert a measurement in kilopascals to a measurement in atmospheres, multiply the pressure by the following conversion ratio: 0.009869 atmospheres/kilopascal.
Since one kilopascal is equal to 0.009869 atmospheres, you can use this simple formula to convert:
atmospheres = kilopascals × 0.009869
The pressure in atmospheres is equal to the pressure in kilopascals multiplied by 0.009869.
For example, here's how to convert 500 kilopascals to atmospheres using the formula above.
atmospheres = (500 kPa × 0.009869) = 4.934616 atm
Kilopascals and atmospheres are both units used to measure pressure. Keep reading to learn more about each unit of measure.
What Is a Kilopascal?
The kilopascal is a multiple of the pascal, which is the SI derived unit for pressure. In the metric system, "kilo" is the prefix for thousands, or 103. Kilopascals can be abbreviated as kPa; for example, 1 kilopascal can be written as 1 kPa.

What Is an Atmosphere?
The atmosphere is a reference measure of pressure equal to 101,325 pascals or 1,013,250 dynes. The atmosphere was originally defined as the pressure of 760 millimeters of mercury at standard gravity at 0 °C, but was later redefined in 1954 to be equal to 1,013,250 dynes.
Atmospheres can be abbreviated as atm; for example, 1 atmosphere can be written as 1 atm.
