1 kcal is equal to 4.184 kJ. A calorie is a unit that is used to measure energy. One calorie refers to the energy needed to raise the temperature of a single kg of water by a single degree celsius in temperature. A Joule is equal to the work done by a force of one newton acting through one metre. The Joule derives its name from English physicist James Prescott Joule. A Joule can also be expressed in electrically terms as one watt-second. One watt-second is the energy released in one second by a current of one ampere through a resistance of one ohm.
