To convert inches of mercury to millimeters of mercury, enter the value in the first field. The result in millimeters of mercury is calculated automatically using the exact conversion factor.

1 inHg = 25.4 mmHg
1 mmHg ≈ 0.0393700787402 inHg

Formula: mmHg = inHg × 25.4
inHg ≈ mmHg × 0.0393700787402

Definitions: 1 inHg = 25.4 mmHg; 1 mmHg = 133.322387415 Pa

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 millimeter of mercury (mmHg) is the pressure at the base of a one-millimeter column of mercury. It is the unit of blood pressure in medicine, for example 120/80 mmHg, and is also used for some barometric and vacuum readings.
