## What is Joules to calories conversion

To convert joules (J) to calories (cal), you can use the conversion factor 0.239006.

Calories = J * 0.239006

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

Calories = 10,000 J * 0.239006 Calories ≈ 2,390.06 cal

Therefore, 10,000 joules 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 joules to calories

### Joules to thermochemical calories

1 calth = 4.184 J

The energy in thermochemical calories E(calth) is equal to the energy in joules E(J) divided by 4.184:

E(cal) = E(J) / 4.184

### Joules to thermochemical calories Example

Convert 600 joules to thermochemical calories.

E(cal) = 600J / 4.184 = 143.4 calth

### Joules to 15°C calories

1 cal15 = 4.1855 J

The energy in 15°C calories E(cal15) is equal to the energy in joules E(J) divided by 4.1855:

E(cal15) = E(J) / 4.1855

### Joules to 15°C calories Example

Convert 600 joules to 15°C calories.

E(cal15) = 600J / 4.1855 = 143.352 cal15

### Joules to large/food calories

1 Cal = 4.184 kJ = 4184 J

The energy in large/food calories E(Cal) is equal to the energy in joules E(J) divided by 4184:

E(Cal) = E(J) / 4184

### Joules to large/food calories Example

Convert 600 joules to food calories.

E(Cal) = 600J / 4184 = 0.1434 Cal
