Atmospheric pressure (P) is the force per unit area exerted against a surface by the weight of the air above that surface. It is commonly measured in pascals (Pa) or atmospheres (atm).
The formula for atmospheric pressure is:
P = ρ - g - h
where:
- P is the atmospheric pressure in pascals (Pa) - ρ is the air density in kilograms per cubic meter (kg/m³) - g is the acceleration due to gravity in meters per second squared (m/s²) - h is the height of the air column in meters (m)
