To convert inches of mercury to millibars, enter the value in the first field. The result in millibars is calculated automatically using the exact conversion factor.
1 inHg = 33.86388640341 mbar
1 mbar ≈ 0.029529983301 inHg
Formula: mbar = inHg × 33.86388640341
inHg ≈ mbar × 0.029529983301
Definitions: 1 inHg = 25.4 mmHg; 1 mbar = 0.001 bar
The inch of mercury (inHg) is the pressure at the base of a one-inch column of mercury. It is used in the United States for barometric pressure in weather reports and for altimeter settings in aviation, where standard sea-level pressure is 29.92 inHg.
The millibar (mbar) is one thousandth of a bar and equals exactly one hectopascal. It is the traditional unit for atmospheric pressure in meteorology and aviation, and it is common for vacuum pressures.
