Calories to Kilogram Converter (Cal to Kg)
Convert Calories to Kilograms (kcal to kg) or Kilograms to Calories (kg to kcal)
This conversion is applicable for body fat
Formula to convert Calories to Kilograms
How many Calories in a Kilo? (kg to cal)
To convert kg of fat to calories, multiply kg by 7716.18
Calories = Kilograms * 7716.18
For example, to convert 0.5 kg to calories, multiply 0.5 by 7716
cal = 0.5 * 7716.18 = 3858 cal
How many Kilos in a Calorie? (cal to kg)
To convert Calories to Kilograms, divide calories by 7716.179. This is for calories to a kilo of body fat
Kilograms = Calories / 7716.179
For example, to find out how much kg is 2000 calories, divide 2000 by 7716
kg = 2000/7716 = 0.47 kg
What is a Calorie?
- A calorie is defined as the heat or energy needed to raise the temperature of 1 gram of water by 1 degree centigrade at a pressure of 1 atmosphere.
- It is also referred to as gram calorie (g-cal) or thermo chemical calorie or 'small' calorie. This is equal to 4.1868 joules of energy.
- The Food Calorie (Calorie with capital C) or kcal is equal to 1000 calories and is defined as the amount of heat needed to raise the temperature of 1 kilogram of water by 1 degree centigrade.
- The energy required for this in terms of joules is 4186.8. In other words, 1 Food Calorie (kcal or Calorie) is equal to 4,186.8 Joules
- This conversion tool is with reference to Food Calorie. All edible items refer to Food Calorie when they mention Calories. The calorific value indicates the amount of energy in kilo calories that it contains.
What is a Kilogram?
- A kilogram is the standard unit of mass
- It is the mass equal to 1000 cubic cm of water and equal to 1000 grams.
- A Kilo is short form of Kilogram and they are same. Abbreviation for Kilogram is 'kg'
- The latest definition of Kilogram is based on Planck's constant 6.626070150 × 10-34 kg m2/s. This is derived from the relationships between Energy, Mass and Frequency
- Calorie and Kilogram are indirectly related through Energy (in Joules or kg m2/s2)
Basis for Calories to Kilograms Conversion
- The relationship between Calorie and Kilogram is not a direct one and there is no accurate formula or equation for the same.
- The basis for weight and calorie is through research and experiments. It has been found that 1 gram of fat contains 9 calories. A gram of protein contains 4 calories. A gram of carbohydrate also contains 4 calories.
- The actual body fat percentage in human adipose tissue is in the range of 70-80% of fat and not 100%. Therefore, 1 gram of body fat is taken to be 7 calories instead of 9 calories.
- Therefore, a 1000 grams or 1 kg of fat is said to contain 7716 calories and it is the energy stored as body fat. This is used as the basis for the conversion of calorie to kg.
- The conversion factor of 0.00013 is derived from the above (1/7716 = 0.00013) Therefore, to convert calorie to kilogram of fat, we divide by 7716 or multiply by 0.00013
- This means that in order to lose one kilogram, you need to reduce your calories by 7,716 what is commonly referred to as 'calorie deficit'. This can be achieved by a combination of diet and exercise. In order to gain 1 kg, you need a surplus of 7716 calories.
