Atmospheric pressure - Wikipedia Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013 25 hPa), which is equivalent to 1,013 25 millibars, [1] 760 mm Hg, 29 9212 inches Hg, or 14 696 psi [2]
How Is Barometric Pressure Measured and Why? - HowStuffWorks Barometric pressure is a measurement of the air pressure in Earth's atmosphere For this reason, it is also known as atmospheric pressure The pressure is created by fluid gas molecules in the air, and it extends in all directions

Barometer - Wikipedia A barometer is a scientific instrument that is used to measure air pressure in a certain environment Pressure tendency can forecast short term changes in the weather Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries
What is Barometric Pressure? Simply put, barometric pressure is the measurement of air pressure in the atmosphere, specifically the measurement of the weight exerted by air molecules at a given point on Earth Barometric pressure changes constantly and is always different depending on where the reading takes place
