## What is Kilojoules to Calories conversion

To convert kilojoules (kJ) to calories (cal), you can use the conversion factor 239.006.

Calories = kJ * 239.006

For example, let's convert 10 kilojoules to calories:

Calories = 10 kJ * 239.006 Calories ≈ 2,390.06 cal

Therefore, 10 kilojoules is approximately equal to 2,390.06 calories.

## Small & large calories

Small calorie (cal) is the energy needed to increase 1 gram of water by 1°C at a pressure of 1 atmosphere.

Large calorie (Cal) is the energy needed to increase 1 kg of water by 1°C at a pressure of 1 atmosphere.

Large calorie is also called food calorie and is used as a unit of food energy.

## How to convert from kilojoules to calories

### Kilojoules to thermochemical calories

1 calth = 0.004184 kJ

1 kJ = 239.0057 calth

The energy in thermochemical calories E(calth) is equal to the energy in kilojoules E(kJ) times 239.0057:

E(cal) = E(kJ) × 239.0057

### Example

Convert 0.6 kilojoules to thermochemical calories.

E(cal) = 0.6kJ × 239.0057 = 143.4 calth

### Kilojoules to 15°C calories

1 cal15 = 0.0041855 kJ

1 kJ = 238.9201 cal15

The energy in 15°C calories E(cal15) is equal to the energy in kilojoules E(kJ) times 238.9201:

E(cal15) = E(kJ) × 238.9201

### Example

Convert 0.6 kilojoules to 15°C calories.

E(cal15) = 0.6kJ × 238.9201 = 143.352 cal15

### Kilojoules to large/food calories

1 Cal = 4.184 kJ

1 kJ = 0.239 Cal

The energy in large/food calories E(Cal) is equal to the energy in kilojoules E(kJ) times 0.239:

E(Cal) = E(kJ) × 0.239

### Example

Convert 0.6 kilojoules to food calories.

E(Cal) = 0.6kJ × 0.239 = 0.1434 Cal
