Convert kilocalorie (th) to megajoule
Please provide values below to convert kilocalorie (th) [kcal (th)] to megajoule [MJ], or Convert megajoule to kilocalorie (th).
1 kcal (th) = 0.004184 MJ. To convert kilocalorie (th) to megajoule, multiply the value by 0.004184; to go the other way, divide by it (1 MJ = 239.005736138 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) = 0.004184 MJ
- 1 MJ = 239.005736138 kcal (th)
- 10 kcal (th) = 0.04184 MJ

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.
Megajoule
A megajoule (MJ) is a unit of energy equal to one million joules.
History/Origin
The megajoule was introduced as part of the metric system to measure large amounts of energy, especially in scientific and engineering contexts, aligning with the SI units established in the 20th century.
Current Use
The megajoule is used in fields such as physics, engineering, and energy industries to quantify large energy quantities, including in energy production, consumption, and scientific research.
