What are the values to mechanical equivalent of heat?

The mechanical equivalent of heat is a value that quantifies the relationship between mechanical energy and thermal energy. Historically, it is represented by the constant ( J ), which is approximately 4.184 joules per calorie. This means that 1 calorie of heat energy is equivalent to about 4.184 joules of mechanical energy. This principle underlies the first law of thermodynamics, illustrating the conversion between different forms of energy.
