Inch of mercury

Inches of mercury, (inHg and "Hg) is a unit of measurement for pressure. It is still used for barometric pressure in weather reports, refrigeration and aviation in the United States. It is the pressure exerted by a column of mercury of 1 inch (2.54 cm) in height at the standard acceleration of gravity. Conversion to metric units depends on the temperature of mercury, and hence its density; typical conversion factors are: In older literature, an "inch of mercury" is based on the height of a column of mercury at 60 °F (15.6 °C) 1 inHg60 °F = 3376.85 Pa
