Hectopascals to millibar
Type a value in hPa to get it in mbar instantly.
Nothing on our list is smaller: a vacuum cleaner is 20× higher. Spread over a fingertip, that is like resting 0.0102 kg on it.
What it means
How much pressure is that?
Tyre and tank figures are gauge pressure, measured above the surrounding air. Weather and altitude figures are absolute.
The math
How to convert hPa to mbar
To convert hectopascals to millibar, multiply by 1.
Example: 10 hPa × 1 = 10 mbar.
In the other direction, 1 mbar = 1 hPa.

About these units
Hectopascals (hPa)
A hectopascal is 100 pascals and is numerically identical to a millibar. Modern weather charts use hPa, with sea level at 1,013 hPa.
Millibar (mbar)
A millibar is a thousandth of a bar and equals one hectopascal. Weather charts still label air pressure in millibars, around 1,013 at sea level.
