eQuest fan static pressure units

edit

I'm attempting to model a school in eQuest and my fan energy seems much too low. In searching for the source of the low fan energy I noticed that the input screen in eQuest for AHU fan static pressure lists "Static in WG" for units, while the SV-A output report lists the units for the AHU fan in "IN-WATER."

What throws me is that the value in both is exactly the same: that is, I've entered a fan static pressue of 0.4 inches hg in eQuest, and the static pressure value which appears in the SV-A report in inches water is also 0.4.

Has anyone encountered this oddity? Anyone aware of what the source might be? I don't yet have a good grasp of how the unit conversions work between eQuest and DOE...
