What does one foot-pound represent?

One foot-pound is the work done by a force of one pound-force acting through a displacement of one foot in the force's direction.

What is the definition of a Btu (th)?

Btu (th) is the heat needed to raise the temperature of one pound of water by one degree Fahrenheit, based on the thermochemical calorie standard.

Why convert foot-pounds to Btu (th)?

Converting foot-pounds to Btu (th) helps relate mechanical energy quantities to thermal energy for use in heating, fuel energy, and HVAC system evaluations.
