1 calorie is equal to 0.001 kcal
When converting 1 calorie to kcal, it equals 0.001 kcal. This means that each calorie is a thousandth of a kilocalorie. The conversion is straightforward because 1 calorie is exactly 1/1000 of a kcal, making the calculation simple and direct.
Introduction
The conversion from calories to kilocalories is a basic unit change in energy measurement. One calorie (cal) is defined as the amount of energy needed to raise 1 gram of water by 1 degree Celsius. Kilocalories (kcal), often called “large calories,” are 1000 calories and used in nutritional contexts.

Conversion Formula
The formula to convert calories to kcal is simple: kcal = calories * 0.001. This works because 1 kcal is equal to 1000 calories. So, dividing or multiplying by 1000 converts between the two units. For example, 500 calories equals 0.5 kcal because 500 * 0.001 = 0.5.
Conversion Example
- Convert 10 calories:
- Multiply 10 by 0.001
- 10 * 0.001 = 0.01
- Result: 10 calories = 0.01 kcal
- Convert 50 calories:
- Multiply 50 by 0.001
- 50 * 0.001 = 0.05
- Result: 50 calories = 0.05 kcal
- Convert 100 calories:
- Multiply 100 by 0.001
- 100 * 0.001 = 0.1
- Result: 100 calories = 0.1 kcal
- Convert 250 calories:
- Multiply 250 by 0.001
- 250 * 0.001 = 0.25
- Result: 250 calories = 0.25 kcal
- Convert 1000 calories:
- Multiply 1000 by 0.001
- 1000 * 0.001 = 1
- Result: 1000 calories = 1 kcal

Conversion Definitions
A calorie (cal) is a unit of energy measuring the amount needed to raise 1 gram of water by 1 degree Celsius. A kilocalorie (kcal) equals 1000 calories, and is used in food energy contexts. Both units are used to quantify energy, but kcal is more common in diet labels.
Conversion FAQs
Why is the calorie sometimes called a small calorie and a large calorie?
The small calorie (cal) measures energy to raise 1 gram of water by 1°C, while the large calorie (kcal) or food calorie measures energy to raise 1 kilogram (1000 grams) of water by 1°C. The term “calorie” often refers to kcal in dietary contexts, causing confusion.
Can I convert calories to joules using this formula?
No, this formula only covers calories and kcal. To convert calories to joules, multiply the calorie value by 4.184. This is because 1 cal equals 4.184 joules, a different conversion factor from kcal.
Is the conversion from calorie to kcal exact or approximate?
The conversion is exact because 1 kcal equals 1000 calories by definition. However, some nutritional labels might round numbers, so small discrepancies can occur in real-world measurements.
