Kilojoules to calories (kJ to Cal) conversion table shows the most common values for the quick reference. Alternatively, you may use the converter to convert any other values.
1 Kilojoule (kJ) = 0.239005736 Calories [Nutritional, Food calorie]
1 Kilojoule (kJ) = 239.005736 Calories
Kilojoule is metric system energy unit (electrical, mechanical or thermal) and equals to 1000 times of the amount of work done by a force of one newton to move an object one meter.
It is also commonly referred to food energy (nutritional energy) and replaced food calorie (or nutritional calorie) in nutrition labels in many countries. The abbreviation is "kJ".
Calorie is a metric energy unit and scientifically defined as the amount of energy to heat 1 gram of water to 1 celsius degree. As a unit of energy, it equals to 4.184 joules.
It is also called a "small calorie" when used in this context and abbreviated as "cal" (with small letters). But calorie in daily life is commonly used as a food energy (also known as large calorie and nutritional calorie) and abbreviated as "Cal" (with capital "C") to avoid confusion.
As a food energy, it is defined as the amount of energy to heat 1 kilogram of water to 1 celsius degree. This is 1000 times higher than the amount for scientific energy unit.
