FORMULA & EXAMPLES
How to convert Standard atmospheres to kilopascals
kPa = atm × 101.325
Multiply the atm reading by 101.325.
Worked examples
1 atm ≈ 101.325 kPa
1 × 101.325 ≈ 101.325
2 atm ≈ 202.65 kPa
2 × 101.325 ≈ 202.65
Frequently asked questions
Does atm to kPa change gauge pressure into absolute pressure?
No. Unit conversion preserves the original pressure reference. Converting a gauge reading to absolute pressure additionally requires the applicable atmospheric pressure.
