#### kcal to calories

One kilocalorie, is equal to the heat needed to raise the temperature of one kilogram of water from 14.5 to 15.5 degrees Celsius. Kilocalories can be abbreviated as kcal; for example, 1 kilocalorie can be written as 1 kcal. When being used to measure nutrition or metabolic processes, the large calorie is used, which is equal to one kilocalorie.

One calorie is equal to the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius. When measuring the energy content in foods, the large calorie, or kilocalorie is used, but it's often still just called a "calorie." When both the calorie and large calorie are used in the same context it is common to refer to the calorie as a "small calorie." Calories can be abbreviated as cal; for example, 1 calorie can be written as 1 cal.

#### 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.

#### How to convert kcal to calories

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 6 kcal to large calories:

E(Cal) = 6 kcal = 6 Cal
