Note: Atmospheric pressure is the pressure exerted by the atmosphere. Gauge pressure is the pressure of a system measured by a gauge, which excludes atmospheric pressure. Absolute pressure is the sum of the available atmospheric pressure and the gauge pressure of the system. Absolute Pressure = Gauge Pressure + Atmospheric Pressure. = 150 psig (gauge pressure) + 14.7 psi (atmospheric pressure) = 164.7 psia, for example.  | ||
