Calories to kcal conversion
Calories to kilocalories (kcal) conversion is the process of converting energy values from calories (cal) to kilocalories. To convert calories to kilocalories, you need to divide the value in calories by 1000.
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
