SAE vs. BHP/wus X-flow heads

[The Richards <smrm@coastalnet.com>]

Is there a forumula for comparing one standard to the other? I would think
some plus/minus would definately be in order since the differences in
'where' they are measured would make a formula problematic. This is just
layman's logic, but would SAE, measured at wheels include more variables
than BHP?
