Just FYI that document was more of a question than anything else, so take it with a grain of salt. It'd be good to have others check the work to make sure it and my conclusions are correct.

Thank you all for your help.
I determined the units for the numerical constants provided in the equations. Now I can meaningfully use the equation that relates K, Q, and dP in both unit systems, which is what I was looking for.
I have attached a pdf with my work. If you would like to look it...
Hello,
I am trying to find some resistances (Cv) for a hydraulic system for which I have the K-factors (K, or (f*L/D)^.5). I found an old copy of Crane's TP-410, which supplies the following:
Cv = Q*(rho/(dp*62.4))^.5 = 29.9*d^2/(f*L/D)^.5 = 29.9*d^2/K^.5
where
rho = density in...
