The amount of force exerted over a surface area caused by the weight of air molecules above it. As elevation increases, fewer air molecules are present.
Therefore, atmospheric pressure always decreases with increasing height. A column of air in cross section, measured from sea level to the top of the
atmosphere, would weigh approximately 14.7 (psi) pounds per square inch. The standard value for atmospheric pressure at sea level is equal to ...
1 atm = 760 mm Hg (millimeters of mercury) = 1013 millibars = 14.7 psi (pounds force per square inch) = 1013.25 hPa (hectopascals).
Welcome to pressure folks, where atmospheric pressure is calculated based on height above or below sea level. I worked for awhile to get these calculators. I tried several times to make my own, but I live at a very odd altitude. I get very strange barometric pressure readings at times. Made it very difficult to produce accurate calculators so I gathered these from around the network, they are accurate as they can be. Some tell you what your pressure should be; some tell you the percents of pressure on you at a given altitude. Others tell you information about the city you live in, such as geographical information, height above sea level, and population, and geographic coordinates on a map. Enjoy the pressure.
