Atmospheric pressure is commonly measured with a barometer. The units used for measuring atmosphere pressure are Pascals(Pa).
Explanation:
- In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes.
- Meteorologists describe the atmospheric pressure by how high the mercury rises.
- Atmospheric pressure is the pressure exerted on a surface area by the weight of the air above the surface of the object.
- One standard atmosphere, which is also referred to as one atmosphere, is equivalent to 1,01,325 pascals or newtons of force per square metre (approximately 14.7 pounds per square inch).
