What is a joule used to measure?

A joule is the SI unit for energy, work, and heat, representing energy transferred by a force of one newton over a meter.

Is pound-force foot the same as torque?

While pound-force foot shares dimensional units with torque, they represent different physical quantities and should not be confused.

Why convert joules to pound-force feet?

Conversions to pound-force feet help express energy in imperial units often used in mechanical engineering and legacy systems.
