Normal atmospheric pressure is 14.7 psi, which means that a column of air one square inch in area rising from the Earth's atmosphere to space weighs 14.7 pounds. ... Normal atmospheric pressure is defined as 1 atmosphere. 1 atm = 14.6956 psi = 760 torr.

Atmospheric pressure is defined as the force per unit area exerted against a surface by the weight of the air above that surface. In the diagram below, the pressure at point "X" increases as the weight of the air above it increases.

(where, as above, a psi is a pound per square inch). Notice that you fill a car tire up to about 30-35 psi and a bike tire to as much as 70-85 psi. In order to demonstrate that there is this pressure acting, we can consider a large canister.

Recall pressure is Force/Area. Atmospheric pressure is about 15 psi. The area of the paper 24in*24in = 576 in**2. Thus the force is 15 lb/in**2 * 276 in**2 = 8640 lb. Quite a lot. Enough to break a stick.

I am in need of the equations used to compute the atmospheric pressure in pounds per square inch (psi) in your. I notice that your atmospheric properties calculator is very accurate. I have to use the psi equivalent of pressure at altitude for an explosive atmosphere test.

Air pressure is the force exerted on you by the weight of tiny particles of air (air molecules). Although air molecules are invisible, they still have weight and take up space. Since there's a lot of "empty" space between air molecules, air can be compressed to fit in a smaller volume.
