air pressure, atmospheric pressure, pressure

the pressure exerted by the atmosphere

barometric pressure

atmospheric pressure as indicated by a barometer

compartment pressure

the air pressure maintained in an air-tight compartment (as in an aircraft)

overpressure

a transient air pressure greater than the surrounding atmospheric pressure

sea-level pressure

the atmospheric pressure reduced by a formula to the pressure at sea level

Type of:

the force applied to a unit area of surface; measured in pascals (SI unit) or in dynes (cgs unit)
