What is a therm (US)?

A therm (US) is a unit of heat energy equal to 100,000 British thermal units (BTU), commonly used in the United States for natural gas measurement.

How is pound-force foot related to energy?

Pound-force foot is an imperial unit representing the work done by applying a force of one pound-force through a displacement of one foot, commonly used to express mechanical work or energy.

Can I use pound-force foot interchangeably for torque and energy?

While pound-force foot has the same dimensional units as torque, they are physically different quantities, so care should be taken not to confuse them.
