FORMULA & EXAMPLES
How to convert Kilopascals to standard atmospheres
atm = kPa ÷ 101.325
Divide the kPa reading by 101.325.
Worked examples
1 kPa ≈ 0.009869232667 atm
1 ÷ 101.325 ≈ 0.009869232667
100 kPa ≈ 0.9869232667 atm
100 ÷ 101.325 ≈ 0.9869232667
Frequently asked questions
Does kPa to atm 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.
