Conversion Formula
The standard formula to convert kilocalories (kcal) to calories (cal) is:
calories = kilocalories × 1000
This formula works because one kilocalorie is defined as 1,000 calories. The calorie here is a small unit of energy, while the kilocalorie is a larger unit used to express food energy.
For example, if you have 28 kcal, multiply 28 by 1,000:
- 28 kcal × 1000 = 28000 calories
That means 28 kcal contains 28,000 calories energy.
Conversion Example
- Example 1: Convert 15 kcal to calories
- Take the kcal value: 15
- Multiply by 1000: 15 × 1000 = 15000
- Result: 15 kcal = 15,000 calories
- Example 2: Convert 42.5 kcal to calories
- Start with 42.5 kcal
- Multiply by 1000: 42.5 × 1000 = 42500
- So, 42.5 kcal equals 42,500 calories
- Example 3: Convert 7.8 kcal to calories
- Begin with 7.8 kcal
- Multiply by 1000: 7.8 × 1000 = 7800
- Therefore, 7.8 kcal is 7,800 calories
- Example 4: Convert 53 kcal to calories
- Starting value: 53 kcal
- Calculate: 53 × 1000 = 53000
- Result: 53 kcal = 53,000 calories

Conversion Definitions
kcal: Kilocalorie, symbolized as kcal, is a unit measuring energy, especially in food. It equals 1,000 small calories and is the unit displayed on nutrition labels to represent the energy content in foods and drinks. It helps users understand the energy intake from what they consume.
calories: Calories, in this context, are a smaller unit of energy, defined as the amount of heat needed to raise 1 gram of water by 1 degree Celsius. It is rarely used alone in food energy measurements, but forms the basis of kilocalories. When multiplied by 1,000, kcal converts to calories.
Conversion FAQs
Why multiply kcal by 1000 to get calories?
Because one kilocalorie is equal to 1,000 calories. The prefix “kilo-” means 1,000 times the base unit. So multiplying the kcal value by 1,000 converts it to the smaller calorie unit.
Are kcal and calories interchangeable terms?
In everyday usage, kcal and calories are often used interchangeably, but technically, 1 kcal equals 1,000 calories. Food energy labels commonly show kcal but call them calories, which can cause confusion.
Can I convert calories to kcal by dividing by 1000?
Yes, to convert calories back to kilocalories, divide the calories value by 1,000. For example, 28,000 calories divided by 1,000 equals 28 kcal.
Is calorie a standard SI unit?
No, calorie is not an SI unit. The SI unit for energy is the joule. However, calorie remains used in nutrition and food science contexts to measure energy content.
Why do nutrition labels show kcal but write “calories”?
This is a convention where “calories” on labels actually means kilocalories. It simplifies the label for consumers but can confuse those trying to convert units precisely.
