Formula
Formula
atm = kPa × 0.009869233
Multiply any value in kilopascals by 0.009869233 to obtain the value in standard atmospheres.
Worked example
Convert 101.325 kPa to atm.
- 01Start with 101.325 kPa.
- 02Multiply by the conversion factor: 101.325 × 0.009869233 = 1 atm.
Result101.325 kPa = 1 atm

FAQ
What is the conversion factor from kPa to atm?
1 kPa equals 0.009869233 atm. To convert, multiply the value in kilopascals by 0.009869233.
How do I convert 1 kPa to atm?
1 kPa = 0.00986923 atm. For any value, multiply by 0.009869233.
How do I convert atm back to kPa?
Divide by the same factor — or equivalently, multiply by 101.325. So 1 atm = 101.325 kPa.
When would I need to convert kilopascal to standard atmosphere?
Pressure conversions between kPa and atm are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
Is the conversion exact?
Yes. Both kPa and atm are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
