About these units
cal (calories (thermochemical)): Small heat quantities in science work.
MJ (megajoules): Fuel energy and large thermal loads.
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.
