How to convert Kilojoules to Calories
Multiply the kilojoules value by 239.006: 1 kJ = 239.006 cal. Going the other way, 1 cal = 0.004184 kJ, so divide by 239.006 or use the Calories to Kilojoules converter.
About these units
Kilojoules (kJ)
A kilojoule is 1,000 joules. Food energy is labelled in kilojoules in many countries; 1 kJ is about 0.239 kilocalories.
Calories (cal)
The calorie used here is the thermochemical calorie, exactly 4.184 joules, roughly the energy needed to warm one gram of water by one degree Celsius. Food calories are actually kilocalories.
