How to convert Mm of Mercury to Inch of Water
Multiply the mm of mercury value by 0.535238: 1 mmHg = 0.535238 inH₂O. Going the other way, 1 inH₂O = 1.86833 mmHg, so divide by 0.535238 or use the Inch of Water to Mm of Mercury converter.
About these units
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.
Inch of Water (inH₂O)
An inch of water is the pressure of a column of water 1 inch high, about 249 pascals. It is used for ventilation ducts and low gas pressures.
