How to Convert Calories to Kilograms

To convert a calorie measurement to a kilogram measurement, multiply the weight by the conversion ratio.

Since one calorie is equal to 0.00013 kilograms, you can use this simple formula to convert:

kilograms = calories × 0.00013

The weight in kilograms is equal to the calories multiplied by 0.00013.

For example, here's how to convert 5,000 calories to kilograms using the formula above.
5,000 kcal = (5,000 × 0.00013) = 0.647989 kg

Calories are a unit of energy, and kilograms are a unit of weight. Keep reading to learn more about each unit of measure.


Converting calories is actually a conversion of energy burned by the body performing work rather than actual weight. When measuring the energy content in foods, the large calorie, or kilocalorie, is used, but it's often still just called a "calorie."

One calorie (large calorie) is equal to the heat needed to raise the temperature of one kilogram of water by 1 degree Celsius.[1] You'll need to burn 3,500 calories more than you eat to lose one pound of weight.[2]

Calories can be abbreviated as kcal; for example, 1 calorie can be written as 1 kcal.


The definition of the kilogram changed in 2019. One kilogram was previously equal to the mass of the platinum-iridium bar, known as the International Prototype of the Kilogram, which was stored in Sèvres, France.

The 2019 SI brochure now defines the kilogram using the Planck constant, and it is defined using the meter and second.[3] It is roughly equal to the mass of 1,000 cubic centimeters of water.

The kilogram, or kilogramme, is the SI base unit for weight and is also a multiple of the gram. In the metric system, "kilo" is the prefix for 103. Kilograms can be abbreviated as kg; for example, 1 kilogram can be written as 1 kg.
