Atmospheres to Kilopascals Converter
How to convert atmospheres to kilopascals
kilopascals = atmospheres × 101.325
To convert atmospheres to kilopascals, multiply the number of atmospheres by 101.325.
1 atm = 101.325 kPa
Examples
- Standard sea-level atmospheric pressure: 1 atm × 101.325 = 101.325 kPa
- 2 atm × 101.325 = 202.65 kPa
Good to know
This is the standard atmosphere (atm), exactly 101,325 Pa. It is not the technical atmosphere (at), which is 1 kgf/cm² or 98,066.5 Pa.

Unit definitions
- Atmosphere (atm)
- The standard atmosphere is defined as exactly 101,325 pascals, approximately the average air pressure at sea level. It is used as a reference pressure in chemistry and physics.
- Kilopascal (kPa)
- A kilopascal is 1000 pascals. It is the common SI unit for tire pressures, weather reports and engineering in metric countries.
