Hectopascals to inches of mercury
Type a value in hPa to get it in inHg 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 inHg
To convert hectopascals to inches of mercury, multiply by 0.02953.
Example: 10 hPa × 0.02953 = 0.2953 inHg.
In the other direction, 1 inHg = 33.8639 hPa.

The units
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.
Inches of mercury (inHg)
Inches of mercury are used in US weather reports and aviation altimeters, where standard pressure is 29.92 inHg.
