# Joules to kilocalories conversion

Joules to kilocalories conversion is the process of converting energy values from joules (J) to kilocalories (kcal). To convert joules to kilocalories, you need to divide the value in joules by the conversion factor 4184.

## What is Joules to kilocalories conversion

To convert joules (J) to kilocalories (kcal), you can use the conversion factor 0.000239006.

Kilocalories = J * 0.000239006

For example, let's convert 10,000 joules to kilocalories:

Kilocalories = 10,000 J * 0.000239006 Kilocalories ≈ 2.39006 kcal

Therefore, 10,000 joules is approximately equal to 2.39006 kilocalories.

## How to convert from joules to kcal

### Joules to thermochemical / food kilocalories

1 kcal_{th} = 4184 J

The energy in joules *E*_{(J)} is equal to the energy in kilocalories *E*_{(kcal-th) }divided by 4184:

*E*_{(kcal)} = * E*_{(J)} / 4184

### Example

Convert 5000 joules to kilocalories.

*E*_{(}_{kcal}_{)} = 5000 J / 4184 = 1.195 kcal

### Joules to international kilocalories

1 kcal_{IT} = 4186.8 J

The energy in joules *E*_{(J)} is equal to the energy in international kilocalories *E*_{(kcal-IT)}
divided by 4186.8:

*E*_{(kcal-IT)} = * E*_{(J)}
/ 4186.8

### Example

Convert 5000 joules to kilocalories.

*E*_{(kcal-IT)} = 5000 J / 4186.8 =
1.194 kcal_{IT}

### Joules to 15°C kilocalories

1 kcal_{15} = 4185.5 J

The energy in joules *E*_{(J)} is equal to the energy in 15°C kilocalories *E*_{(kcal15)}
divided by 4185.5:

*E*_{(}_{kcal15}_{)} = * E*_{(J)} / 4185.5

### Example

Convert 5000 joules to kilocalories.

*E*_{(kcal15)} = 5000 J / 4185.5 = 1.195 kcal_{15}

### Joules to 20°C kilocalories

1 kcal_{20} = 4182 J

The energy in joules *E*_{(J)} is equal to the energy in 20°C kilocalories *E*_{(kcal20)}
divided by 4182:

*E*_{(}_{kcal20}_{)} = * E*_{(J)} / 4182

### Example

Convert 5000 joules to kilocalories.

*E*_{(}_{kcal20}_{)} = 5000 J / 4182 = 1.196 kcal_{20}
