The first category is the small calorie or gram calorie (written with lower-case ‘c’, expressed with the symbol ‘cal’ ) is defined as the amount of heat or energy required at one atmosphere pressure to raise the temperature of one gram of water by one degree Celsius. The other category, the large Calorie (with upper case letter ‘C’) also kilogram calorie (indicated with symbols: Cal, kcal) is expressed in terms of the kilogram, not the gram and so the definition is similar – the energy required at a pressure of one atmosphere to increase the temperature of one kilogram of water by one degree Celsius. The second ones are the calories a person gains by eating. They are also called food calories.

A joule is an SI unit of measurement for work or energy, which equals the work done by a force of one newton acting to move an object through a length of one meter in the direction of the object’s motion. In the terms of electric currents, a joule is the energy dispersed as heat in one second by a current of one ampere through a resistance of one ohm.
