Which term is defined as the weight of air, also known as atmospheric pressure?

Explanation:
Atmospheric pressure is the force per unit area exerted by the weight of the air above and around us. It comes from gravity pulling on the air column in the atmosphere, and it’s what a barometer measures when we talk about barometric pressure. Gauge pressure is the pressure above ambient air (absolute pressure minus atmospheric), while vacuum pressure is pressure below that ambient level. Since the definition points to the weight of air and the ambient environment, the term that fits best is atmospheric pressure.
