What is the relation between gauge pressure and absolute pressure?

Also question is, how do you convert gauge pressure to absolute pressure?
Absolute pressure = Guage pressure + Atmospheric pressure. So for converting gauge pressure into absolute pressure, just add atmospheric pressure in it.
Likewise, what does gauge pressure mean? Gauge pressure is the pressure measured relative to the ambient atmospheric pressure. So the air around us has a gauge pressure of millibars/PSI/whatever. So gauge pressure is absolute pressure minus atmospheric pressure.
Similarly, it is asked, which equation describes the relationship between gauge pressure absolute pressure and atmospheric pressure?
This happens because of Pascal's principle. The total pressure, or absolute pressure, is thus the sum of gauge pressure and atmospheric pressure: Pabs = Pg + Patm where Pabs is absolute pressure, Pg is gauge pressure, and Patm is atmospheric pressure.
What is an absolute pressure?
Definition of absolute pressure. : total pressure at a point in a fluid equaling the sum of the gauge and the atmospheric pressures.
