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.

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 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)
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)
Convert 6 kcal to large calories:
E(Cal) = 6 kcal = 6 Cal
