Convert calorie (IT) to millijoule
Please provide values below to convert calorie (IT) [cal (IT)] to millijoule [mJ], or Convert millijoule to calorie (IT).
1 cal (IT) = 4186.8 mJ. To convert calorie (IT) to millijoule, multiply the value by 4186.8; to go the other way, divide by it (1 mJ = 0.000238845896627 cal (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 cal (IT) = 4186.8 mJ
- 1 mJ = 0.000238845896627 cal (IT)
- 10 cal (IT) = 41868 mJ
- 100 cal (IT) = 418680 mJ
How to Convert Calorie (It) to Millijoule
1 cal (IT) = 4186.8 mJ
Example: convert 15 cal (IT) to mJ:
15 cal (IT) = 15 × 4186.8 mJ = 62802 mJ

Calorie (It)
The calorie (cal) is a unit of energy traditionally used to quantify the amount of heat required to raise the temperature of one gram of water by one degree Celsius at standard atmospheric pressure.
History/Origin
The calorie was originally defined in the 19th century as a unit of heat energy in thermodynamics. It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts. The 'small calorie' (cal) is distinct from the 'large calorie' (kcal), which is commonly used in food energy labeling.
Current Use
Today, the calorie is primarily used in nutrition to measure the energy content of foods and beverages, although the SI unit of energy, the joule, is increasingly preferred in scientific and technical fields.
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.
