Conversion Result
1 calorie equals 0.001 kcal.
One calorie is a small unit of energy, and when converted to kilocalories, it becomes 0.001 kcal, which is a larger unit often used in dietary contexts. This means that one calorie is just a thousandth of a kcal, making kcal a more practical measure for food energy.
Introduction
The conversion from calories to kilocalories involves understanding the relationship between these units of energy. Since 1 kcal is equal to 1000 calories, converting between them is straightforward. Knowing this helps in nutritional calculations and food labeling.

Conversion Formula
The formula to convert calories to kcal is simple: kcal = calories * 0.001. This works because 1 kcal equals 1000 calories, so dividing calories by 1000 gives the kcal value. For example, converting 500 calories: 500 * 0.001 = 0.5 kcal.
Conversion Example
- Example 1: Convert 2 calories to kcal.
- Apply formula: 2 * 0.001 = 0.002 kcal.
- Example 2: Convert 10 calories to kcal.
- 10 * 0.001 = 0.01 kcal.
- Example 3: Convert 25 calories to kcal.
- 25 * 0.001 = 0.025 kcal.
- Example 4: Convert 100 calories to kcal.
- 100 * 0.001 = 0.1 kcal.
- Example 5: Convert 0.5 calories to kcal.
- 0.5 * 0.001 = 0.0005 kcal.

Conversion Definitions
A calorie is a small unit of energy, measuring the heat needed to raise the temperature of water by one degree Celsius. A kilocalorie, also called a large calorie, equals 1000 calories and is used for food energy measurements in nutrition.
Kcal is a unit representing 1000 calories, used to express the energy content of food, exercise, and metabolic activities. It simplifies understanding large energy quantities and is the standard in dietary contexts, contrasting the small calorie measurement.
Conversion FAQs
How many calories are in one kcal?
One kilocalorie equals 1000 calories. This means when you see a food label with 200 kcal, it actually contains 200,000 calories in the smaller measurement. The kcal simplifies reporting and calculations involving large energy amounts.
Why is there a difference between calorie and kcal?
The difference exists because calories are small units of energy, while kcal are larger units used for convenience in food and metabolic measurements. Using kcal avoids dealing with very large numbers, making it easier to interpret energy values.
Can I convert calories to kcal for exercise energy calculations?
Yes, simply divide the calorie count by 1000 to get kcal. For example, burning 500 calories during exercise equals 0.5 kcal. This helps in understanding energy expenditure and planning diets or workouts with larger energy units.
Is 1 calorie the same as 1 kcal?
No, they are different units. 1 calorie is a small unit of energy, whereas 1 kcal equals 1000 calories. The term calorie is often used informally to refer to kcal, but technically they differ by a factor of 1000.
How do I convert calories to kcal in nutrition labels?
Simply divide the calorie number by 1000. Nutrition labels usually list energy in kcal, so if you need to convert from calories, do this division to understand the energy in kcal units.
