About these units
ft·lbf (foot-pounds-force): US mechanical work and impact energy.
J (joules): The SI unit of energy: one newton metre.
The BTU used here is the International Table BTU (1,055.056 J). A foot-pound of energy (ft·lbf) is the same dimension as a lbf·ft of torque, but the two are different physical quantities.
