Real-world reference

Standard atmospheric pressure is 1,013.25 mbar. A strong hurricane has a central pressure below 950 mbar. In hectopascals, that gives you: 1 mbar = 1 hPa, 10 mbar = 10 hPa, 100 mbar = 100 hPa.

Frequently asked questions

How many hectopascals are in 1 millibar?
1 millibar equals 1 hectopascals.
How do I convert millibars to hectopascals?
Multiply the millibar value by 1. So x mbar × 1 = the equivalent in hPa.
What is 5 millibars in hectopascals?
5 millibars equals 5 hectopascals.
What is 10 millibars in hectopascals?
10 millibars equals 10 hectopascals.
What is 100 millibars in hectopascals?
100 millibars equals 100 hectopascals.
How do I convert back from hectopascals to millibars?
Multiply the hectopascal value by 1. For example, 1 hPa = 1 mbar.
Is the millibar bigger than the hectopascal?
No. 1 millibar is smaller than 1 hectopascal. It takes 1 millibars to equal 1 hectopascal.
Are these conversion factors exact?
The factor is derived directly from the SI definitions of millibar and hectopascal; the displayed value is rounded for readability, and the browser computes using IEEE 754 double-precision arithmetic.

About the millibar and the hectopascal

The millibar

The millibar (mbar) equals exactly 100 Pa — identical to the hectopascal (hPa) used in modern meteorology. Weather maps almost universally use mbar/hPa for sea-level pressure isobars.

The hectopascal

The hectopascal (hPa) equals exactly 100 Pa — numerically identical to the millibar. It is the unit modern meteorological services use on official weather charts and forecasts, having formally replaced the millibar in most national weather services since the 1980s.
