Frequently asked questions
What is the source unit in this conversion?
The source unit is the atmosphere (atm). A standard atmosphere is exactly 101,325 pascals.
What is the destination unit in this conversion?
The destination unit is the kilopascal (kPa). Kilopascal is 1000 pascal units.
How do I convert atmosphere to kilopascal?
Multiply the atmosphere value by 101.325. For example, 10 atm × 101.325 = 1013.25 kPa.
Is the atmosphere to kilopascal conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in atmosphere needs to be compared with, or reported in, kilopascal, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert kilopascal back to atmosphere?
Yes. Multiply the kilopascal value by 0.009869 to get atmosphere.

About this conversion
This page converts atmosphere (atm) to kilopascal (kPa) within the pressure converter.
A standard atmosphere is exactly 101,325 pascals. Kilopascal is 1000 pascal units.
The formula is kilopascal = atmosphere × 101.325, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
Use the calculator above for instant results, or the table below for common atmosphere values already converted to kilopascal.
