Convert calorie (th) to megajoule
Please provide values below to convert calorie (th) [cal (th)] to megajoule [MJ], or Convert megajoule to calorie (th).
1 cal (th) = 4.184e-06 MJ. To convert calorie (th) to megajoule, multiply the value by 4.184e-06; to go the other way, divide by it (1 MJ = 239005.736138 cal (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 cal (th) = 4.184e-06 MJ
- 1 MJ = 239005.736138 cal (th)
- 10 cal (th) = 4.184e-05 MJ
- 100 cal (th) = 0.0004184 MJ
How to Convert Calorie (Th) to Megajoule
1 cal (th) = 4.184e-06 MJ
Example: convert 15 cal (th) to MJ:
15 cal (th) = 15 × 4.184e-06 MJ = 6.276e-05 MJ

Calorie (Th)
The calorie (th) is a unit of energy used to quantify the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie (th) was historically used in the context of thermochemistry and nutrition, originating from the calorie concept in the 19th century. It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.
Current Use
Today, the calorie (th) is primarily used in nutrition labeling and food energy measurements, especially in regions where the thermochemical calorie is still recognized, although the joule is the SI standard.
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.
