WebAug 6, 2024 · The Barometric Formula – Air is a gas, but for purposes of calculating atmospheric pressure, you could regard it as a fluid, and calculate the pressure at sea level using the expression for fluid pressure. This expression is: where ρ is the density of air, g is the acceleration of gravity, and h is the height of the atmosphere.
Atmospheric pressure, also known as 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 1013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approxi…
