How to convert Inch of Mercury to Mm of Mercury
Multiply the inch of mercury value by 25.4001: 1 inHg = 25.4001 mmHg. Going the other way, 1 mmHg = 0.0393699 inHg, so divide by 25.4001 or use the Mm of Mercury to Inch of Mercury converter.
About these units
Inch of Mercury (inHg)
An inch of mercury is about 3,386 pascals. US weather reports and aircraft altimeters give barometric pressure in inHg, typically near 29.92.
Mm of Mercury (mmHg)
A millimeter of mercury is the pressure exerted by a column of mercury 1 mm high, about 133.3 pascals. Blood pressure is measured in mmHg.
