pressure on a planet's surface caused by the amount of gas in the atmosphere. Atmospheric pressure is commonly measured in pounds per sqare inch, kilopascal, or milimeters of mercury. The atmospheric pressure at the Earth's surface is 14.7 pounds per sq. in., meaning that 1 sq. in. of air extending vertically from sea level to outer space weighs 14.7 pounds.
