Atmospheric pressure is expressed in several different systems of units: millimetres (or inches) of mercury, pounds per square inch (psi), dynes per square centimetre, millibars (mb), standard atmospheres, or kilopascals. Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per ...

Atmospheric pressure is the pressure exerted by the force of air on the earth surface. It is also classified as barometric pressure. With the help of mercury barometer atmospheric pressure can be determined. It is closely related or approximated to the hydrostatic pressure. It can be differed from high altitude and low altitude.

Standard pressure supports 760 millimeters in a mercurial barometer (760 mmHg ). This is about 29.9 inches of mercury, and represents approximately 14.7 pounds per inch (14.7 lb/in2). Imagine a column of air measuring one inch square, extending straight up into space beyond the atmosphere. The air in such a column ...
