About these units
MJ (megajoules): Fuel energy and large thermal loads.
Wh (watt-hours): Battery and small-load energy.
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.
