From Fluent Documentation:

Static Pressure (in the Pressure... category) is the static pressure of the fluid. It is a gauge pressure expressed relative to the prescribed operating pressure. The absolute pressure is the sum of the Static Pressure and the operating pressure. Its unit quantity is pressure.
Reason we use an operating pressure is for numerical round-off reasons.
