FORMULA & EXAMPLES
How to convert Pascals to kilopascals
kPa = Pa ÷ 1000
Divide the Pa reading by 1000.
Worked examples
1 Pa ≈ 0.001 kPa
1 ÷ 1000 ≈ 0.001
1000 Pa ≈ 1 kPa
1000 ÷ 1000 ≈ 1
Frequently asked questions
Does Pa 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.
