Convert kilocalorie (IT) to joule
Please provide values below to convert kilocalorie (IT) [kcal (IT)] to joule [J], or Convert joule to kilocalorie (IT).
1 kcal (IT) = 4186.8 J. To convert kilocalorie (IT) to joule, multiply the value by 4186.8; to go the other way, divide by it (1 J = 0.000238845896627 kcal (IT)). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kcal (IT) = 4186.8 J
- 1 J = 0.000238845896627 kcal (IT)
- 10 kcal (IT) = 41868 J

Kilocalorie (It)
A kilocalorie (kcal) is a unit of energy equal to 1,000 calories, commonly used to measure the energy content of food and beverages.
History/Origin
The kilocalorie originated in the 19th century as a measure of heat energy, primarily used in nutrition and thermodynamics. It became standard in dietary contexts to quantify food energy intake.
Current Use
Today, the kilocalorie is widely used in nutrition to express the energy content of foods and beverages, and in scientific contexts related to energy measurement in biological and physical systems.
Joule
The joule (J) is the SI unit of energy, work, and heat, defined as the work done when a force of one newton acts over a distance of one meter.
History/Origin
The joule was named after James Prescott Joule in 1889 to honor his work in energy and thermodynamics. It was adopted as the SI unit of energy in 1948.
Current Use
The joule is widely used in physics, engineering, and everyday contexts to quantify energy, work, and heat in various applications, including electricity, mechanics, and thermodynamics.
