Conversion formula
Atmosphere to Kilopascal formula: value in kpa = value in atm × 101.325.
Kilopascal to Atmosphere formula: value in atm = value in kpa × 0.0098692326671601.
How to convert Atmosphere to Kilopascal
To convert Atmosphere to Kilopascal, multiply the value in atm by 101.325. This gives the result in kpa.
For example, 1 atm = 101.325 kpa and 10 atm = 1013.25 kpa.
What is Atmosphere?
Atmosphere (atm): A reference pressure for comparing gas conditions, rather than a reading of today’s weather. 1 atm = 101 325 Pa.
What is Kilopascal?
Kilopascal (kPa): A practical pressure scale for tyres, gas supplies and engineering specifications. 1 kPa = 1 000 Pa.
FAQ
