     Atmospheric pressure

     • 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.

   What does air pressure mean?

   • Air pressure, atmospheric pressure, or barometric pressure, is the pressure exerted over a surface by the weight of an air mass (and its molecules) above it. How Heavy Is Air? Air pressure is a difficult concept. How can something invisible have mass and weight? Air has mass because it is made up of a mixture of gases that have mass.

   How is air pressure measured?

   • At observation stations around the world, the air pressure reading, regardless of the observation station elevation, is converted to a value that would be observed if that instrument were located at sea level. The two most common units in the United States to measure the pressure are "Inches of Mercury" and "Millibars".

   What is atmospheric pressure in physics?

   • Atmospheric pressure is the force per unit area exerted by a body of air above a specified area (called an atmospheric column). It is expressed in several different systems of units, including millimeters (or inches) of mercury, pounds per square inch (psi), millibars (mb), or standard atmospheres.
