Convert calorie (IT) to megajoule
Please provide values below to convert calorie (IT) [cal (IT)] to megajoule [MJ], or Convert megajoule to calorie (IT).
1 cal (IT) = 4.1868e-06 MJ. To convert calorie (IT) to megajoule, multiply the value by 4.1868e-06; to go the other way, divide by it (1 MJ = 238845.896627 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) = 4.1868e-06 MJ
- 1 MJ = 238845.896627 cal (IT)
- 10 cal (IT) = 4.1868e-05 MJ
- 100 cal (IT) = 0.00041868 MJ
How to Convert Calorie (It) to Megajoule
1 cal (IT) = 4.1868e-06 MJ
Example: convert 15 cal (IT) to MJ:
15 cal (IT) = 15 × 4.1868e-06 MJ = 6.2802e-05 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 It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts.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.
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.
