Convert kilocalorie (IT) to gigajoule
Please provide values below to convert kilocalorie (IT) [kcal (IT)] to gigajoule [GJ], or Convert gigajoule to kilocalorie (IT).
1 kcal (IT) = 4.1868e-06 GJ. To convert kilocalorie (IT) to gigajoule, multiply the value by 4.1868e-06; to go the other way, divide by it (1 GJ = 238845.896627 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) = 4.1868e-06 GJ
- 1 GJ = 238845.896627 kcal (IT)
- 10 kcal (IT) = 4.1868e-05 GJ

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.
Gigajoule
A gigajoule (GJ) is a unit of energy equal to one billion joules, used to measure large amounts of energy such as in power generation and fuel consumption.
History/Origin
The gigajoule was introduced as part of the International System of Units (SI) to provide a standard measure for large-scale energy quantities, especially in scientific and industrial contexts, gaining prominence in the 20th century.
Current Use
Gigajoules are commonly used today to quantify energy in fields like energy production, consumption, and engineering, particularly for large-scale systems such as power plants, fuel storage, and energy audits.
