1 calorie equals 0.001 kcal.
A calorie (cal) is a unit of energy, and when we convert it to kilocalories (kcal), we divide by 1000 because 1 kcal is 1000 calories. Therefore, 1 calorie is a thousandth of a kcal, showing the scale difference between these units.
Conversion Result and Explanation
The conversion of 1 calorie to kcal results in 0.001 kcal. This is because 1 kcal equals 1000 calories, so converting from calories to kcal involves dividing the calorie value by 1000.

Conversion Formula
The formula to convert calories to kcal is simple: kcal = calories / 1000. This works because 1 kilocalorie is equal to 1000 calories, making the division the necessary operation. For example, 500 calories divided by 1000 equals 0.5 kcal, showing how the units relate.
Conversion Example
- Convert 10 calories:
- Start with 10 calories.
- Divide 10 by 1000.
- Result is 0.01 kcal.
- Convert 250 calories:
- Begin with 250 calories.
- Divide 250 by 1000.
- Result is 0.25 kcal.
- Convert 1000 calories:
- Use 1000 calories as the starting point.
- Divide 1000 by 1000.
- Result is 1 kcal.

Conversion Definitions
A calorie (cal) is a unit of energy measurement, representing the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius. Kilocalorie (kcal) is 1000 times larger, used in food energy values, often called “Calories” with a capital C.
Kilocalorie (kcal) measures energy content, especially in nutrition, equivalent to 1000 calories. It quantifies the energy released during metabolic processes, and is the standard unit for food energy, widely used in dietary contexts and energy calculations.
Conversion FAQs
What does it mean when I say 1 calorie equals 0.001 kcal?
This indicates that one calorie is a thousandth of a kilocalorie, meaning to convert calories to kcal, you divide the number of calories by 1000. It helps standardize energy measurements across different fields, especially nutrition and physics.
Can I convert calories to kcal manually?
Yes, simply divide the calorie amount by 1000 to get the kcal equivalent. For example, 200 calories divided by 1000 equals 0.2 kcal. This manual calculation is straightforward and helps understand the scale difference between units.
Why is the conversion factor 1000 between calories and kcal?
This factor exists because 1 kcal is defined as 1000 calories, establishing a larger unit to measure energy in food and biological systems, making it easier to express larger amounts of energy without using cumbersome numbers.
Are there any other units related to calorie conversions I should know?
Yes, other units include the joule, where 1 calorie equals approximately 4.184 joules. Converting between joules and kcal involves different formulas, but for calorie to kcal, the division by 1000 is standard.
Is the calorie used in physics the same as the calorie in nutrition?
They are related but differ slightly; the small calorie (cal) used in physics is the energy needed to heat 1 gram of water by 1°C, whereas the food calorie (kcal) is 1000 of these calories and used in nutrition to describe energy in foods.
