How to convert kcal to calories

How to convert kilocalories (kcal) to calories (cal).

Small & large calories

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

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

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

kcal to cal - small kilocalories to small calories

1 kcal = 1000 cal

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

E_(cal) = 1000 × E_(kcal)

Example

Convert 6kcal to small calories:

E_(cal) = 1000 × 6kcal = 6000 cal

kcal to Cal - small kilocalories to large calories

1 Cal = 1 kcal

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

E_(Cal) = E_(kcal)

Example

Convert 6kcal to large calories:

E_(Cal) = 6kcal = 6 cal

kCal to cal - large kilocalories to small calories

1 kCal = 1000000 cal

The energy in small calories (cal) is equal to 1000000 times the energy in large kilocalories (kCal):

E_(cal) = 1000000 × E_(kCal)

Example

Convert 6kCal to small calories:

E_(cal) = 1000000 × 6kCal = 6000000 cal

kCal to Cal - large kilocalories to large calories

1 kCal = 1000 Cal

The energy in large calories (Cal) is equal to 1000 times the energy in large kilocalories (kCal):

E_(Cal) = 1000 × E_(kCal)

Example

Convert 6kCal to large calories.

E_(Cal) = 1000 × 6kCal = 6000 Cal
