## How to convert from kilojoules to kcal

### Kilojoules to thermochemical / food kilocalories

1 kcalth = 4.184 kJ

The energy in kilojoules E(kJ) is equal to the energy in kilocalories E(kcal-th) divided by 4.184:

E(kcal) = E(kJ) / 4.184

#### Example

Convert 5 kilojoules to kilocalories.

E(kcal) = 5 kJ / 4.184 = 1.195 kcal

### Kilojoules to international kilocalories

1 kcalIT = 4.1868 kJ

The energy in kilojoules E(kJ) is equal to 4.1868 times the energy in international kilocalories E(kcal-IT):

E(kcal-IT) = E(kJ) / 4.1868

#### Example

Convert 5 kilojoules to kilocalories.

E(kcal-IT) = 5 kJ / 4.1868 = 1.194 kcalIT

### Kilojoules to 15ºC kilocalories

1 kcal15 = 4.1855 kJ

The energy in kilojoules E(kJ) is equal to 4.1855 times the energy in 15ºC kilocalories E(kcal15):

E(kcal15) = E(kJ) / 4.1855

#### Example

Convert 5 kilojoules to kilocalories.

E(kcal15) = 5 kJ / 4.1855 = 1.195 kcal15

### Kilojoules to 20ºC kilocalories

1 kcal20 = 4.182 kJ

The energy in kilojoules E(J) is equal to 4.182 times the energy in 20ºC kilocalories E(kcal20):

E(kcal20) = E(kJ) / 4.182

#### Example

Convert 5 kilojoules to kilocalories.

E(kcal20) = 5 kJ / 4.182 = 1.196 kcal20
