Calorific Value Definition, Calculating Method, Formula

Calorific value is the energy or amount of heat produced as a result of the complete combustion of a unit volume of the substance. It is important as it gives the value of fuel or food in numbers which can be calculated with a formula. As fuels and food are daily consumed by humans, it is important to track their usage and also is significant
