What does pound-force inch measure?

Pound-force inch measures small mechanical work, representing the work done by one pound-force acting through a one-inch displacement.

Btu (th), or thermochemical British thermal unit, is a unit of energy defined as the heat to raise one pound of water by one degree Fahrenheit using a thermochemical calorie basis.

Can I use this tool to convert torque directly to heat energy?

No, because pound-force inch measures mechanical work and Btu (th) measures thermal energy, the conversion is only accurate for energy equivalence calculations with proper context.
