What is the SI unit of mechanical equivalent of heat?


The mechanical equivalent of heat implies that motion and heat are interchangeable, and that a defined amount of work generates the same amount of heat in all situations if the work is completely converted to heat energy. The mathematical expression for the mechanical equivalent of heat is,

\(\begin{array}{l}J = \frac{W}{q}\end{array} \)


W = The amount of heat required to generate heat

q = Amount of heat

SI unit of mechanical equivalent

The SI unit of mechanical equivalent of heat is Joules/ calorie.
