## What is Kilocalories to kilojoules conversion

To convert kilocalories (kcal) to kilojoules (kJ), you can multiply the value in kilocalories by 4.184.

kJ = kcal * 4.184

For example, let's convert 100 kilocalories to kilojoules:

kJ = 100 kcal * 4.184 kJ = 418.4 kJ

Therefore, 100 kilocalories is equal to 418.4 kilojoules.

## How to convert from kcal to kilojoules

### Thermochemical / food kilocalories to kilojoules

1 kcalth = 4.184 kJ

The energy in kilojoules E(kJ) is equal to 4.184 times the energy in thermochecmical / food kilocalories E(kcal):

E(kJ) = 4.184 × E(kcal-th)

### Example

Convert 0.3 kcalth to kilojoules.

E(kJ) = 4.184 × 0.3 kcalth = 1.2552 kJ

### International kilocalories to kilojoules

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(kJ) = 4.1868 × E(kcal-IT)

### Example

Convert 0.3 kcalIT to kilojoules.

E(kJ) = 4.1868 × 0.3kcalIT = 1.25604 kJ

### 15°C kilocalories to kilojoules

1 kcal15 = 4.1855 kJ

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

E(kJ) = 4.1855 × E(kcal15)

### Example

Convert 0.3 kcal15 to kilojoules.

E(kJ) = 4.1855 × 0.3kcal15 = 1.25565 kJ

### 20°C kilocalories to kilojoules

1 cal20 = 4.182 kJ

The energy in kilojoules E(kJ) is equal to 4.182 times the energy in 20°C kilocalories E(kcal20):

E(kJ) = 4.182 × E(kcal20)

### Example

Convert 0.3 kcal20 to kilojoules.

E(kJ) = 4.182 × 0.3kcal20 = 1.2546 kJ
