Atmospheric pressure

That pressure is called atmospheric pressure , or air pressure. It is the force exerted . The air around you has weight, and it presses against everything it touches. A altimeter can be set for QNH or QFE.

Both are a method of reducing . Air is a tangible material substance and as a result has mass. Any object with mass is influenced by the universal force . Detailed weather maps show the atmospheric pressure by means of curved lines called isobars. As with an isotherm for temperature, an isobar connects all points with the same.
