Calorific Value - Definition, Calculating Method, Formula,
The calorific value of fuel can be defined as the amount of heat produced by the complete combustion of one unit of any fuel. The unit depends upon the type of fuel, for example, coal is a solid fuel so it is measured in weight units whereas we use volume units for any gaseous or liquid fuel. Therefore, the calorific value for them will be,

Fuel Calorific Values | CNG Europe
The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under “normal” (standard) conditions (i.e. to 0 o C and under a pressure of 1,013 mbar). The combustion process generates water vapor and certain techniques may be used to recover the quantity of heat contained in this water vapor by condensing it.
