Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure. Various units are used to express pressure.
Atmospheric pressure is the amount of force exerted over a surface area, caused by the weight of air above it. Since fewer air molecules are present at higher elevations, atmospheric pressure decreases as altitude increases. The most common unit of measure for atmospheric pressure is the millibar (mb). On Earth, the average atmospheric pressure at sea level is 1,013 mb, while on Mars it is only 7.5 mb.
