Atmospheric pressure or air pressure is measured by a barometer. A mercury barometer measures the pressure by noting the length of mercury which is supported by the weight of the atmosphere.
Pressure is force per unit area. Pressure is measured in various units. Standard unit for air pressure is mm of Hg. Bar is also another unit for the pressure.
