What Units Are Used to Measure Air Pressure?

Answer

Air pressure or atmospheric pressure is measured using an instrument known as a barometer, which is also used in forecasting the weather and determining the altitude. Air pressure or atmospheric pressure is the force of each unit area exerted against a surface by the air density above that surface.

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.
