Pressure loss calculations differ. Imperial uses inches of water column (in. w.g.); metric uses Pascals (Pa). The Guide must teach how to interpret metric fan curves (Pa vs. m³/s) and set up Revit’s duct pressure loss calculator using metric roughness factors (mm). A weak guide would simply convert numbers; a strong one explains why 250 Pa is a typical static pressure for a small VAV system.
