About the units

Millibar (mbar)

The millibar (mbar) is a unit of pressure in the metric system. One millibar equals 100 pascals (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 millibar?

There is 1 hectopascal in one millibar, and this value is exact by definition.

How do I convert millibars to hectopascals?

Multiply the number of millibars by 1. For example, 10 mbar × 1 = 10 hPa.

How many millibars are in one hectopascal?

One hectopascal equals 1 millibar. That is the reverse factor, 1 ÷ 1.

What is 10 millibars in hectopascals?

10 mbar = 10 hPa.

Is this mbar 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.
