# 1000 kilojoules (kJ) converted to Calories (kcal)

1000 kilojoules (kJ) are equal to 239 calories (kcal). 1000kJ is an often sought conversion for food energy, because it is a convenient round number which converts to a round calorie value (239). 1000kJ is about one tenth of the kilojoules eaten by the average adult in a day.The conversion between kilojoules (kJ) and calories (Cal), specifically kilocalories (kcal), can be useful when estimating energy values in the context of nutrition. The accurate conversion factors are as follows:

1 kilojoule (kJ) = 0.239 kilocalories (kcal)
1 kilocalorie (kcal) = 4.184 kilojoules (kJ)

## Calculation

To convert kilojoules to kilocalories, you can multiply the kilojoule value by 0.239. This conversion factor accounts for the difference in energy measurement between kilojoules and kilocalories. For example, if you have an energy value of 1000 kilojoules (kJ), you can estimate the equivalent in kilocalories (kcal) by multiplying it by 0.239: 1000 kJ * 0.239 = 239 kcal.

Conversely, to convert kilocalories to kilojoules, you need to multiply the kilocalorie value by 4.184. This conversion factor ensures an accurate estimation of energy in kilojoules based on the kilocalorie measurement. For instance, if you have an energy value of 500 kilocalories (kcal), you can estimate the equivalent in kilojoules (kJ) by multiplying it by 4.184: 500 kcal * 4.184 = 2092 kJ.

It’s important to note that kilocalories (kcal) are commonly referred to as “Calories” in nutritional contexts. Thus, when you see the term “Calories” mentioned in food labels or discussions about energy intake, it usually means kilocalories. To avoid confusion, it’s helpful to remember that 1 kilocalorie (kcal) is equivalent to 1 Calorie (capital C) and that the symbol “kcal” represents kilocalories.

By understanding these conversion factors and accurately estimating energy values in either kilocalories or kilojoules, you can make more informed decisions regarding your nutrition and energy intake.  Use the calcount Calorie Converter to find a different conversion, or look up other values below:
