@MatthewSteen does gauge pressure use the same units as static pressure?

No, static pressure (e.g. for fans) is measured in in wc (inches water column) and gauge pressure is measured in psig (lb/in2 gauge). The SI unit is Pa (Pascals).

Just in case you are interested, in QUDT the first would be unit:IN_H2O and the second is unit:LB_F-PER-IN2. Note that the second unit is distinct from the pound of mass per square inch, unit:LB-PER-IN2.
