The mechanical equivalent of heat is a concept that relates mechanical energy to thermal energy. It quantifies the amount of mechanical work required to produce a unit of heat. Historically, this concept was pivotal in the development of thermodynamics. The most well-known value for the mechanical equivalent of heat was determined by the British scientist James Prescott Joule in the mid-19th century.
