FORMULA & EXAMPLES
How to convert Pascals to standard atmospheres
atm = Pa ÷ 101325
Divide the Pa reading by 101325.
Worked examples
1 Pa ≈ 0.000009869232667 atm
1 ÷ 101325 ≈ 0.000009869232667
1000 Pa ≈ 0.009869232667 atm
1000 ÷ 101325 ≈ 0.009869232667
Frequently asked questions
Does Pa 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.
