1 calorie equals 0.001 kcal
Converting 1 calorie to kcal results in 0.001 kcal. This means that one calorie is a thousandth part of a kilocalorie, which is the standard unit used in food energy descriptions.
The detailed explanation: since 1 kcal equals 1000 calories, dividing 1 calorie by 1000 gives the equivalent in kcal. This conversion helps in understanding food energy content in more familiar units used in nutrition labeling and energy calculations.

Conversion Formula
The formula to convert calories to kcal is simple: divide the number of calories by 1000. This works because 1 kcal equals 1000 calories. For example, if you have 500 calories, dividing by 1000 gives 0.5 kcal. This calculation scales down the calorie value to kcal units, making it easier to compare and understand energy content in food.
Conversion Example
- Convert 250 calories to kcal:
- Step 1: Start with 250 calories.
- Step 2: Divide 250 by 1000 to get kcal.
- Step 3: 250 / 1000 = 0.25 kcal.
- Convert 100 calories to kcal:
- Step 1: Number of calories is 100.
- Step 2: Divide 100 by 1000.
- Step 3: 100 / 1000 = 0.1 kcal.
- Convert 50 calories to kcal:
- Step 1: Calories are 50.
- Step 2: Divide 50 by 1000.
- Step 3: 50 / 1000 = 0.05 kcal.

Conversion Definitions
Calorie
A calorie is a unit of energy that measures how much energy food provides or how much energy the body expends. It is the amount of heat needed to raise the temperature of 1 gram of water by 1°C. Often used in nutrition and food energy calculations.
Kcal (Kilocalorie)
A kilocalorie, or kcal, equals 1000 calories, and is the standard unit in food energy labeling. It represents the total energy in food, and is what people commonly refer to as a “calorie” when talking about diet and nutrition.
Conversion FAQs
Why do food labels use kcal instead of calories?
Food labels use kcal because it simplifies large energy values into manageable numbers. Since 1 kcal equals 1000 calories, labeling in kcal makes it easier to express and compare energy contents of different foods without dealing with large numbers.
Can I convert kcal back to calories easily?
Yes, to convert kcal to calories, multiply the kcal value by 1000. For example, 2 kcal equals 2000 calories. This reverse calculation helps when translating nutritional data into smaller energy units for scientific calculations or personal understanding.
Is the calorie used in physics the same as the nutritional calorie?
No, the calorie in physics refers to the small calorie, the amount of heat to raise 1 gram of water by 1°C, while the nutritional calorie, or kcal, is 1000 of these small calories. The nutritional calorie is the common measurement for energy content in food.
