Air pressure is caused by the weight of air above an area pressing on surfaces below. It is measured in two ways: absolute barometric pressure and relative barometric pressure. Absolute barometric pressure uses the vacuum of space as its standard. Relative barometric pressure is measured relative to air pressure at sea level. Barometric pressure measures the weight of the air in the atmosphere pressing down against us. On average, the atmosphere exerts 14.7 pounds per square inch (psi) on the Earth’s surface.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.A. Differences in air pressure because of the weather or changes in altitude can have noticeable effects on the human body, though some people are more sensitive than others. Low barometric ...

Barometric pressure is the weight of the atmosphere pressing down on the Earth.
