FORMULA & EXAMPLES
How to convert Pascals to hectopascals
hPa = Pa ÷ 100
Divide the Pa reading by 100.
Worked examples
1 Pa ≈ 0.01 hPa
1 ÷ 100 ≈ 0.01
1000 Pa ≈ 10 hPa
1000 ÷ 100 ≈ 10
Frequently asked questions
Does Pa to hPa 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.
