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. The pressure on the summit of Mount Everest is about 0.3 atm. Calculate it with the air pressure at altitude formula: Choose the parameters: h = 8949 m, and T = -30 °C. Fix the reference values at h0 = 0 m and P0 = 1 atm. Use the air pressure at altitude formula: P = P0 × exp(-g × M × (h - h0)/(R × T)=The Barometric Formula. Starting at some point in midair, the change in pressure associated with a small change in height can be found in terms of the weight of the air.
