The calorie is a unit of energy defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius. It is widely used to measure the energy content of food and beverages, where the term often refers to the kilocalorie (or large calorie). Although largely superseded by the joule in the International System of Units, the calorie remains a common measurement in nutrition and daily life.
