Air pressure is the force exerted on an object or area by the weight of surrounding air particles.
Atmospheric pressure is the force that the weight of the air above puts on any part of surface of the earth. Most of the time, atmospheric pressure is considered equivalent (or nearly so) to the hydrostatic pressure, which is the weight of the air above the point where the measurement is being taken.
