I’m used to is TSFC as in “Thrust specific fuel consumption”. That is, lbs of fuel burned, per lb of thrust produced, per hour.

Small typo there;
TSFC = lb/hr/lbf or kg/hr/kN UNQUOTE

XP, I don't see any typo in what I had written in the first line. It appears to me to be the same as what you wrote, although for clarity I might write your TSFC equation as:

TSFC = (lb/hr)/lbf

Here's a link that explains it a bit more if anyone is interested:
