Convert calorie (nutritional) to joule
Please provide values below to convert calorie (nutritional) [Cal] to joule [J], or Convert joule to calorie (nutritional).
1 Cal = 4186.8 J. To convert calorie (nutritional) to joule, multiply the value by 4186.8; to go the other way, divide by it (1 J = 0.000238845896627 Cal). 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 = 4186.8 J
- 1 J = 0.000238845896627 Cal

Calorie (Nutritional)
A calorie (Cal) is a unit of energy used to measure the amount of energy provided by food and beverages, specifically representing the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie was first introduced in the 19th century as a unit to quantify energy in nutrition. It has since become a standard measure in dietary and nutritional contexts, although the scientific community often prefers the joule as the SI unit of energy.
Current Use
Calories are widely used in nutrition to quantify the energy content of food and beverages, helping consumers manage dietary intake and energy balance. The term 'Calorie' with a capital 'C' typically refers to kilocalories (kcal), which are equivalent to 1,000 small calories.
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.
