### What is Meant by the Absolute Pressure?

The absolute pressure is defined as a total pressure at a point in the fluid, which is equal to the sum of gauge pressure and the atmospheric pressure. Gauge pressure means a pressure which is relative to the atmospheric pressure. Gauge pressure is positive for the pressure higher than the atmospheric pressure, and it is negative for the pressure below than the atmospheric pressure. The formula for atmospheric pressure is given by

Absolute Pressure = Gauge pressure + Atmospheric Pressure.
