**To convert kilojoules (kJ) to calories (cal) use this calculator, the conversion factor is 1 kJ = 0.239006 cal, and 1000 kJ are equals to 239.01 cal. **

Caloriesare a non-SI unit of energy commonly used in food nutrition labels and exercise calculations. It’s important to note that when we typically refer to “calories” in food, we’re actually talking about kilocalories (kcal).

## Kilojoules to Calories Conversion Formula

The formula for converting **kilojoules** to **calories** is:

**1 kJ = 0.239006 cal****1 cal = 4.184 kJ**

Kilojoules (kJ) | Conversion Equation | Calories (kcal) |
---|---|---|

100 kJ | 100 × 0.239006 | 23.9 kcal |

500 kJ | 500 × 0.239006 | 119.5 kcal |

1000 kJ | 1000 × 0.239006 | 239.0 kcal |

2000 kJ | 2000 × 0.239006 | 478.0 kcal |

4184 kJ | 4184 × 0.239006 | 1000.0 kcal |

## How to Convert Kilojoules to Calories

To convert **kilojoules** to **calories**, multiply the number of **kilojoules** by 0.239006.

For example, if you have **500 kJ**, you can calculate the calories like this:

**500 kJ × 0.239006 = 119.503 cal**

So, **500 kilojoules** is equal to about **119.5 calories**.

And to convert **2500 kJ** to **calories**: **2500 kJ × 0.239006 = 597.515 kcal**

## How many kJ are 1000 calories?

To find out how many **kilojoules** are in **1000 calories**, we use the reverse conversion:

**1000 kcal × 4.184 = 4184 kJ**

Therefore, **1000 calories is equivalent to 4184 kilojoules**.

This conversion is particularly useful when comparing international food labels, as some countries use **kJ** while others use **kcal**.

## What is a kilocalorie?

A **kilocalorie** (kcal) is a unit of energy equal to **1000 calories**. It’s important to understand that when we casually refer to “**calories**” in nutrition and dieting, we’re actually talking about **kilocalories**.

One **kilocalorie** is the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius at standard atmospheric pressure.

In scientific contexts, a **calorie** (cal) is a much smaller unit, and **1 kcal = 1000 cal**. However, in everyday usage, “**calorie**” and “**kilocalorie**” are often used interchangeably, which can lead to confusion.
