## What is Calories to kcal conversion

Calories and kilocalories (kcal) are often used interchangeably. 1 kilocalorie is equal to 1 calorie.

So, to convert calories (cal) to kilocalories (kcal), you can simply divide the value in calories by 1000.

kcal = cal / 1000

For example, let's convert 1000 calories to kilocalories:

kcal = 1000 cal / 1000 kcal = 1 kcal

Therefore, 1000 calories is equal to 1 kilocalorie (kcal).

## 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 calories to kcal

### cal to kcal - small calories to small kilocalories

1 kcal = 1000 cal

The energy in small kilocalories (kcal) is equal to the energy in small calories (cal) divided by 1000:

E(kcal) = E(cal) / 1000

##### Example

Convert 6000cal to small kcal:

E(kcal) = 6000cal / 1000 = 6 kcal

### Cal to kcal - large calories to small kilocalories

1 kcal = 1 Cal

The energy in small kilocalories (kcal) is equal to the energy in large calories (Cal):

E(kcal) = E(Cal)

##### Example

Convert 6Cal to kcal:

E(kcal) = 6Cal = 6kcal
