hPa to Pascals Converter (hPa to Pa)

How to convert hectopascals to pascals

FormulaPa = hPa × 100

Multiply the value in hectopascals by 100. To go the other way, multiply by 0.01 (or divide by 100).

A hectopascal is larger than a pascal: one hectopascal contains 100 pascals.

About the units

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).

Pascal (Pa)

One newton per square metre — a very small pressure. Atmospheric pressure is about 101,325 Pa.

Frequently asked questions

How many pascals are in one hectopascal?

There are 100 pascals in one hectopascal, and this value is exact by definition.

How do I convert hectopascals to pascals?

Multiply the number of hectopascals by 100. For example, 10 hPa × 100 = 1,000 Pa.

How many hectopascals are in one pascal?

One pascal equals 0.01 hectopascals. That is the reverse factor, 1 ÷ 100.

What is 10 hectopascals in pascals?

10 hPa = 1,000 Pa.

Is this hPa to Pa 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.
