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