Atmospheric pressure, also known as air pressure or barometric pressure, is the pressure within the atmosphere of Earth. The standard atmosphere is a unit of pressure defined as 101,325 Pa, which is equivalent to 1,013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.
Atmospheric pressure is the force that the air above a surface exerts on that surface due to gravity. The air has mass and weight, and it presses down on everything it touches. The more air there is above a surface, the higher the atmospheric pressure. The less air there is above a surface, the lower the atmospheric pressure. Atmospheric pressure changes with altitude, temperature, and weather conditions.
Instruments used to measure atmospheric pressure.
Atmospheric pressure is measured by instruments such as barometers or aneroids. A barometer uses a column of mercury or a metal disk to balance the weight of the air. An aneroid uses a spring or a bellows to measure the change in the shape of a metal disk due to the air pressure. Atmospheric pressure is expressed in different units, such as millimeters of mercury, pounds per square inch, millibars, standard atmospheres, or kilopascals.
Aspects that atmospheric pressure affects..
Atmospheric pressure affects many aspects of life on Earth, such as the weather, the wind, and the breathing of living beings. Low pressure usually means cloudy and rainy weather, while high pressure usually means clear and sunny weather. Wind is caused by the difference in pressure between two areas. Breathing is easier at lower altitudes, where the pressure is higher, than at higher altitudes, where the pressure is lower.
