The correct abbreviation for calorie is "Cal."
The large calorie, kilogram calorie, dietary calorie or food calorie approximates the energy needed to increase the temperature of 1 kilogram of water by 1 °C.

the measure of energy from food
The definition of the joule is based on more general principles. The calorie is defined by properties specific to water.
The definition of a calorie is that, it's the energy needed to increase the temperature of 1 kilogram of water by 1 °C.
That is the definition of a calorie. It is equal to 4.1868 joules.
A calorie is the amount of heat required to warm 1 gram of water one degree Centigrade. A Calorie spelt with a big "C" is a kilocalorie and is used in evaluating food energy. It is the heat required to raise 1 kilogram of water one Centigrade degree. On an energy basis a calorie is 41 840 000 ergs.
Depends on how high you want to raise the gram of water ;).
Its a calorie
Roughly 4.18400 joules Raising 1 gram of water 1 degree c requires 1 calorie (the definition of calorie includes the actual starting temperature, I think something like 3 degrees celsius). 1 calorie = 4.18400 joules
The definition of a calorie has to do with the specific haet of water. The gram calorie (abbreviated "cal") is the amount of energy needed to heat one gram of water by one degree celsius (centigrade). The kilogram calorie (abbreviated "C") is the amount of energy needed to heat one kilogram of water by one degree celsius. Thus one C equals one kcal or "kilo calorie" often found on food packs enegry declaration and such. One cal equals about 4.2 Joules which is the scientific standar unit for energy.
A nutritional Calorie is 1000 times a chemical calorie.
The difference between a calorie and a Calorie is calorie is a smaller unit than Calorie and it takes 1000 calorie's to make a Calorie. The Calorie (kilocalorie, kcal) is 1000 calories - a more useful unit and widely used.
