Detailed explanation-1: -The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.

Detailed explanation-2: -pressure exerted by air is called atmospheric pressure. it is equal to 1atm.

Detailed explanation-3: -Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1, 013.25 × 103 dynes per square centimetre, 1, 013.25 millibars, one standard atmosphere, or 101.325 kilopascals.

Detailed explanation-4: -The atmospheric pressure at a point is defined as the force acting normally on a unit area around that point, due to the total height of the air column of the atmosphere above it. That pressure is known as atmospheric pressure, also known as air pressure.

Detailed explanation-5: -Fountain bottle, ping pong funnel as well as million doller bet are examples of atmospheric pressure.
