Blood pressure
We express atmospheric pressure or barometric pressure in millimeters of mercury (Hg).
The units for pCO2 are typically expressed in millimeters of mercury (mmHg) or in kilopascals (kPa).
The complete unit of measurement for blood pressure, including a systolic reading of 120 millimeters of mercury, is expressed as mmHg. This unit indicates the pressure exerted by the blood against the walls of the arteries, with "mm" representing millimeters and "Hg" standing for mercury, which is the substance historically used in barometers and sphygmomanometers.
mm Hg means millimeters of mercury.
mmHg represents the height of a column of mercury (Hg) in millimeters (mm) (as opposed to inches of mercury (inHg)). Since there are 10 mm (millimeters) in a centimeter, simply divide the mmHg by 10 and you find that 535mmHg is 53.5 centimeters Hg (cHg?).
The unit of true vapour pressure is typically expressed in millimeters of mercury (mmHg) or kilopascals (kPa).
2,456 millimeters is 2.456 meters.

The conversion factor from millimeters of mercury (mmHg) to pascals (Pa) is 133.322.

The density of mercury is 13.534, compared to '1' for water. So the water columnis 13.534 times as high as the mercury column at the same pressure.(30 inches of water) x (25.4 millimeters/inch) / 13.534 = 56.3 millimeters of mercury
