infoA millimeter of mercury (mmHg) is a non-SI unit of pressure.
It is defined as the pressure exerted at the base of a column of mercury 1 mm high, when the density of the fluid is 13.5951 g/cm³ (this occurs at 0°C or 32°F), at a place where the acceleration of gravity is 9.80665 m/s².
1 mmHg is roughly equal to 1 Torr.
