What is Gauge pressure ?

Gauge pressure, also called overpressure, is the pressure of a system above atmospheric pressure. Gauge pressure is zero-referenced against ambient air (or atmospheric) pressure, so gauge pressure readings include the pressure from the weight of the atmosphere.

How do you find atmospheric pressure?

Atmospheric pressure is the pressure caused by the mass of our gaseous atmosphere. It can be measured using mercury in the equation atmospheric pressure = density of mercury x acceleration due to gravity x-height of a column of mercury. Atmospheric pressure can be measured in atm, torr, mm Hg, psi, Pa, etc.
