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).
mm Hg means millimeters of mercury.
The unit of true vapour pressure is typically expressed in millimeters of mercury (mmHg) or kilopascals (kPa).
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?).
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
