What is Btu (th) used for?

Btu (th) is used to rate heating and cooling equipment, express energy content in fuels and appliances, and size HVAC and hot-water systems.

What does foot-pound measure?

Foot-pound measures mechanical energy or work, such as torque in mechanical assemblies, energy in ballistics, and small amounts of mechanical work.

Can I use this converter for torque values?

Yes, since torque shares the same dimensions as energy, the foot-pound unit is commonly used for specifying torque values.
