Calorie

A measurement of the energy content of food. The body needs calories as "fuel" to perform all of its functions, such as breathing, circulating the blood and physical activity. When a person is sick, their body may need extra calories to fight fever or other problems.

Calorie
"calorie": a unit of measurement defined as 4.184 absolute joules or the amount of energy it takes to raise the temperature of one gram of water from 15 to 16 degrees Celsius (or 1/100th the amount of energy needed to raise the temperature of one gram of water at one atmosphere pressure from 0 degrees C to 100 degrees C). Food calories are actually equal to 1,000 calories (1 food calorie = 1 kilocalorie)

Calorie
as defined in Glossary of Terms

One energy calorie is equivalent to 4.2 joules. Thus, it takes 500,000 calories of energy to boil a pot of coffee. One food calorie equals 1,000 energy calories.

Calorie

The amount of heat needed to raise the temperature of one gram of water at 15 degrees centigrade one degree centigrade. Compare with British Thermal Unit.

Calorie

A unit of energy-producing potential in food.

Calorie

A measurement of the energy content of food. The body needs calories as to perform its functions, such as breathing, circulating the blood, and physical activity. When a person is sick, their body may need extra calories to fight fever or other problems.

Calorie

A unit of energy defined as that amount of energy required to raise the temperature of one gram of water by one degree Celsius (the gram-calorie or small calorie), equal to 4.1855 joules.

The kilogram calorie or large calorie (Kcal, kg-cal, or Cal) is 1000 times as large as a calorie.
