Gauge Pressure Formula

The gauge pressure is the difference between the absolute pressure and the atmospheric pressure and is positive for pressures above atmospheric pressure and negative for pressures below it. Whereas absolute pressure is the sum of gauge and atmospheric pressure. Calculate the gauge pressure of a fluid with respect to the absolute pressure and the atmospheric pressure using the below-given simple gauge pressure formula with the basic subtraction operation.


Gauge Pressure = Absolute Pressure - Atmospheric Pressure
