Calorie
A calorie is the amount of heat energy needed to increase a mililiter of water 1 degree centigrade, the calorie we talk about in foods is really a kilocalorie, that is the amount of energy needed to increase a liter of water 1 degree centigrade... So if you eat a food that is 500 calories that food if burned completely has enough energy to heat a liter of water 500 degrees centigrade.
