## What you should know about kiloJoules and kiloCalories

### How many kiloCalories are in one kiloJoule?

**Thermochemical Calories**

1 kJ = 0.23900573614 kcal_{th}

**International calories**

1 kJ = 0.23884589663 kcal_{IT}

**15ºC calories**

1 kJ = 0.23892008123 kcal_{15}

**20ºC calories**

1 kJ =0.23912003826 kcal_{20}

### How many kiloJoules are in one kiloCalorie?

**Thermochemical kiloCalories**

1 kcal_{th} = 4.184 kJ

**International kiloCalories**

1 kcal_{IT} = 4.1868 kJ

**15ºC kiloCalories**

1 kcal_{15} = 4.1855 kJ

**20ºC kiloCalories**

1 kcal_{20} = 4.182 kJ

**Conversion Example:**

If we want to convert 8 kiloJoules in calories, then we will proceed as following:

**Kilojoules to Thermochemical Kilocalories**

*E _{(kcal-th)} = E_{(kJ)} / 4.184 = 8 / 4.184 = 1.9120 kcal_{th}*

**Kilojoules to International Kilocalories**

*E*

_{(kcal-IT)}= E_{(kJ)}/ 4.1868 = 8 / 4.1868 = 1.9108 kcal_{IT}**Kilojoules to 15ºC Kilocalories**

*E*

_{(kcal15)}= E_{(kJ)}/ 4.1855 = 8 / 4.1855 = 1.9114 kcal_{15}**Kilojoules to 20ºC Kilocalories**

*E*

_{(kcal20)}= E_{(kJ)}/ 4.182 = 8 / 4.182 = 1.9130 kcal_{20}Definition of **kiloJoule** provided by Cambridge Dictionary

a unit of measurement equal to 1,000 joules (= measure of energy or work done)

Definition of **kiloCalorie** provided by Oxford Dictionaries

A unit of energy of 1,000 calories (equal to 1 large calorie).

Definition of **kiloCalorie** provided by Vocabulary.com

a unit of heat equal to the amount of heat required to raise the temperature of one kilogram of water by one degree at one atmosphere pressure; used by nutritionists to characterize the energy-producing potential in food

We eat food to produce energy for our body. Our digestive system is able to convert almost all food into energy. Carbohydrates, proteins and fats can all be converted into energy by our body. Among all of these, carbohydrates are the preferred fuel of our body.

Food energy used to be measured in calories (cal), but now the international measurement for food energy is kilojoule (kJ). These measurement units help us measure how much energy we consume for different activities and how much energy contains our food.

## Energy as kJ and kcal

If miles are the unit of measure for distance, in the same way kJ and kcal are measurement units for energy.

The kcal’s are of various types and they can be measured as large kcal’s (nutritional kilocalories) or small kcal’s. Small kilocalories should not be confused with large kilocalories (nutritional kilocalories). Small kcal’s are used by scientists to measure the amount of energy required to heat water.

The kcal can be converted in kJ, which is the international system of nutritional energy measurement. That is why we designed this converter, to help people who want to convert old unit of measurement for energy from kcal to kJ.

### What are kj and kcal an how can be used

Kilojoules and Kilocalories are two energy units. Kilojoules and Kilocalories units are used in various fields of activity such as physics, chemistry and other industries. This calculator is useful both for those who’s working in these fields of activity but also for students who study energies as Kilojoules and Kilocalories at school.

Our Kilojoules to Kilocalories converter is especially designed to make your calculations fast. You just need to enter Kilojoules value on the first box and the converter will do the rest for you and automatically convert Kilojoules to Kilocalories.

Also you have formula for converting Kilojoules to Kilocalories if you need that in your calculations, but we recommend you to use the Kilojoules to Kilocalories converter because is very fast and accurate for simple conversions.
