Absolute Pressure Calculation
The calculator can calculate the absolute pressure or gauge pressure or atmospheric pressure as selected from drop-down based on given appropriate values. Pressure is the force per unit area applied to any object in a direction perpendicular to the surface. Pressure is defined as the normal force per unit area of a surface.
Absolute Pressure: P_{a} = P_{g} + P_{at}
Gauge Pressure: P_{g} = P_{a} - P_{at}
Atmospheric Pressure: P_{at} = P_{a} - P_{g}
where, P_{a} = Absolute Pressure, P_{g} = Gauge Pressure, P_{at} = Atmospheric Pressure.
Gauge Pressure: P_{g} = P_{a} - P_{at}
Atmospheric Pressure: P_{at} = P_{a} - P_{g}
where, P_{a} = Absolute Pressure, P_{g} = Gauge Pressure, P_{at} = Atmospheric Pressure.
