Simply, heat is a form of energy. It is the energy formed due to the movement of atoms and molecules within a material. Higher the movement of atoms, higher is the heat dissipated. Thus the SI unit of heat is same as that of Energy,that is joule. read more

The joule (/ dʒ uː l /; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N⋅m). read more
