Wiktionary

  1. calorie(Noun)

    (physics and chemistry, obsolete) the gram calorie or small calorie, a non-SI unit of energy, equivalent to approximately 4.2 joules. This unit was widely used in chemistry and physics, being the amount of energy needed to raise the temperature of 1 gram of water by 1u00B0C.

  2. calorie(Noun)

    kilogram calorie or large calorie. A unit of energy 1000 times larger than the gram calorie. It is equivalent to the gram kilocalorie, approximately 4.2 kilojoules.

Webster Dictionary

  1. Calorie(noun)

    the unit of heat according to the French standard; the amount of heat required to raise the temperature of one kilogram (sometimes, one gram) of water one degree centigrade, or from 0¡ to 1¡. Compare the English standard unit, Foot pound.

Freebase

  1. Calorie

    The name calorie is used for two units of energy. ⁕The small calorie or gram calorie is the approximate amount of energy needed to raise the temperature of one gram of water by one degree Celsius. ⁕The large calorie, kilogram calorie, dietary calorie, nutritionist's calorie or food calorie, which is the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius. The large calorie is thus equal to 1000 small calories or one kilocalorie. Although these units are part of the metric system, they now have been superseded in the International System of Units by the joule. One small calorie is approximately 4.2 joules. The factors used to convert calories to joules are numerically equivalent to expressions of the specific heat capacity of water in joules per gram or per kilogram. The conversion factor depends on the definition adopted. In spite of its non-official status, the large calorie is still widely used as a unit of food energy in the US, UK and some other Western countries. The small calorie is also often used in chemistry as the method of measurement is fairly straightforward in most reactions, though the amounts involved are typically expressed in thousands as kcal, an equivalent unit to the large calorie.
