Convert kilocalorie (th) to kilojoule
Please provide values below to convert kilocalorie (th) [kcal (th)] to kilojoule [kJ], or Convert kilojoule to kilocalorie (th).
1 kcal (th) = 4.184 kJ. To convert kilocalorie (th) to kilojoule, multiply the value by 4.184; to go the other way, divide by it (1 kJ = 0.239005736138 kcal (th)). 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 (th) = 4.184 kJ
- 1 kJ = 0.239005736138 kcal (th)
- 10 kcal (th) = 41.84 kJ
- 100 kcal (th) = 418.4 kJ
How to Convert Kilocalorie (Th) to Kilojoule
1 kcal (th) = 4.184 kJ
Example: convert 15 kcal (th) to kJ:
15 kcal (th) = 15 × 4.184 kJ = 62.76 kJ

Kilocalorie (Th)
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 unit to quantify heat energy, especially in nutrition and thermodynamics. It was widely adopted in the early 20th century for dietary energy measurement.
Current Use
Today, the kilocalorie is primarily used in nutrition to express the energy content of food and drinks, although it is often simply called a 'calorie' in everyday language.
Kilojoule
A kilojoule (kJ) is a unit of energy equal to 1,000 joules, used to quantify energy transfer or work done.
History/Origin
The kilojoule was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring energy, especially in fields like nutrition and physics, replacing the joule for larger quantities.
Current Use
The kilojoule is widely used in nutrition to express food energy content, in physics and engineering to measure energy transfer, and in various scientific and industrial applications within the 'Energy' converter category.
