Convert calorie (IT) to joule
Please provide values below to convert calorie (IT) [cal (IT)] to joule [J], or Convert joule to calorie (IT).
1 cal (IT) = 4.1868 J. To convert calorie (IT) to joule, multiply the value by 4.1868; to go the other way, divide by it (1 J = 0.238845896627 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) = 4.1868 J
- 1 J = 0.238845896627 cal (IT)
- 10 cal (IT) = 41.868 J
- 100 cal (IT) = 418.68 J
How to Convert Calorie (It) to Joule
1 cal (IT) = 4.1868 J
Example: convert 15 cal (IT) to J:
15 cal (IT) = 15 × 4.1868 J = 62.802 J

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 It has historically been used in nutrition and physics, but has largely been replaced by the joule in scientific contexts.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.
Joule
The joule (J) is the SI unit of energy, work, and heat, defined as the work done when a force of one newton acts over a distance of one meter.
History/Origin
The joule was named after James Prescott Joule in 1889 to honor his work in energy and thermodynamics. It was adopted as the SI unit of energy in 1948.
Current Use
The joule is widely used in physics, engineering, and everyday contexts to quantify energy, work, and heat in various applications, including electricity, mechanics, and thermodynamics.
