How to convert pascals to hectopascals
hPa = Pa × 0.01Multiply the value in pascals by 0.01. To go the other way, multiply by 100 (or divide by 0.01).
A pascal is smaller than a hectopascal: it takes 100 pascals to make one hectopascal.

About the units
Pascal (Pa)
One newton per square metre — a very small pressure. Atmospheric pressure is about 101,325 Pa.
Hectopascal (hPa)
One hundred pascals, numerically equal to a millibar. Weather maps show sea-level pressure in hPa (around 1013). One hectopascal equals 100 pascals (Pa).
Frequently asked questions
How many hectopascals are in one pascal?
There are 0.01 hectopascals in one pascal, and this value is exact by definition.
How do I convert pascals to hectopascals?
Multiply the number of pascals by 0.01. For example, 10 Pa × 0.01 = 0.1 hPa.
How many pascals are in one hectopascal?
One hectopascal equals 100 pascals. That is the reverse factor, 1 ÷ 0.01.
What is 10 pascals in hectopascals?
10 Pa = 0.1 hPa.
Is this Pa to hPa converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
