Convert calorie (th) to millijoule
Please provide values below to convert calorie (th) [cal (th)] to millijoule [mJ], or Convert millijoule to calorie (th).
1 cal (th) = 4184 mJ. To convert calorie (th) to millijoule, multiply the value by 4184; to go the other way, divide by it (1 mJ = 0.000239005736138 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) = 4184 mJ
- 1 mJ = 0.000239005736138 cal (th)
- 10 cal (th) = 41840 mJ
- 100 cal (th) = 418400 mJ
How to Convert Calorie (Th) to Millijoule
1 cal (th) = 4184 mJ
Example: convert 15 cal (th) to mJ:
15 cal (th) = 15 × 4184 mJ = 62760 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 It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.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.
Millijoule
A millijoule (mJ) is a unit of energy equal to one thousandth of a joule, where 1 joule equals 1 newton meter or 1 kg·m²/s².
History/Origin
The millijoule is derived from the SI base unit joule, with the prefix 'milli' indicating a factor of 10⁻³. It has been used in scientific and engineering contexts to measure small amounts of energy, especially in fields like electronics and biomechanics.
Current Use
The millijoule is commonly used today to quantify small energy quantities in electronics, biomedical applications, and energy measurements where precision at a small scale is required.
