atm to kPa Converter - Standard Atmosphere to Kilopascal
Standard Atmosphere (atm) to Kilopascal (kPa)
Direct answer
1 atm = 101.325 kPa
kPa = atm × 101.325
Converter
Conversion formula
kPa = atm × 101.325
atm = kPa × 0.009869232667
Example: 10 atm = 10 × 101.325 = 1,013.25 kPa.

Explanation of the atm to kPa conversion factor
This conversion factor is based on the defined values of both units in the pascal base unit. A standard atmosphere is defined as 101,325 Pa, and a kilopascal is defined as 1,000 Pa.
Definition
The standard atmosphere (atm) is a unit of pressure defined as exactly 101,325 pascals. The kilopascal (kPa) is a metric unit equal to exactly 1,000 pascals.
Principle
To convert between the two, express both pressures in the shared base unit (pascal), then calculate the ratio. Dividing the pascal value of an atmosphere by the pascal value of a kilopascal gives the factor 101.325.
Assumptions
- The conversion uses the exact, defined values for the standard atmosphere and the kilopascal.
- The pascal is the common base unit for this conversion.
Cautions
- The conversion is exact only for the defined standard atmosphere (101,325 Pa). Other 'atmosphere' definitions may exist.
- Rounding may be necessary depending on the required precision of your calculation.
