Introduction:

The energy value of food is determined by burning the food and measuring the energy that is released as heat.  Food and other fuels are rated by how much energy a certain mass of the fuel gives off as heat when burned.
Calorie ( c)  and kilocalorie ( C ), are units of energy.  With the International System of Units (SI),  a quantity of heat is measured in joules, the SI unit for all forms of energy.
1 calorie = 4.184 J.
