Step-by-Step
How to Convert Kilocalories to Calories
Converting kilocalories to calories is simple when you use the correct conversion factor.
The Formula
Kilocalories and calories are both units of energy used in nutrition, chemistry, thermodynamics, and energy comparisons. This page uses the exact relationship 1 kilocalorie = 1,000 calories.
To convert calories back to kilocalories, divide calories by 1,000.
How to Turn Kilocalories into Calories — Step by Step
Write down the kilocalorie value
Identify the number of kilocalories you want to convert — for example, 10 kcal.
Multiply by 1,000
10 kcal × 1,000 = 10,000 calories. This gives you the equivalent energy in calories.
Label your answer
Always write the unit (cal or calories) after the number so the result is clear and unambiguous.

What Is the Difference Between Kilocalories and Calories?
Kilocalories and calories are both units of energy. A kilocalorie is equal to 1,000 small calories. In nutrition, the term “Calorie” with a capital C is often used to mean 1 kilocalorie, but this page converts kilocalories (kcal) to calories (cal).
The relationship used on this page is: 1 kilocalorie = 1,000 calories. To convert kilocalories to calories, multiply the number of kilocalories by 1,000.
For example, 0.5 kcal = 500 cal, 1 kcal = 1,000 cal, and 10 kcal = 10,000 cal.
This conversion is useful in nutrition tracking, food energy calculations, chemistry, thermodynamics, academic work, and general energy comparisons.
