Conversion Formula
The conversion formula is simple: multiply the value in kcal by 1000 to get the value in calories. Since 1 kcal equals 1000 calories, the formula is:
Calories = kcal × 1000
This works because “kilo” means 1000, so one kilocalorie means 1000 calories. To convert 28 kcal:
- Start with 28 kcal.
- Multiply 28 by 1000.
- 28 × 1000 = 28000 calories.
Conversion Example
- Convert 15 kcal to calories:
- Take 15 kcal.
- Multiply by 1000: 15 × 1000 = 15000 calories.
- Result: 15000 calories.
- Convert 42.5 kcal to calories:
- Start with 42.5 kcal.
- 42.5 × 1000 = 42500 calories.
- This is the equivalent energy amount.
- Convert 7 kcal to calories:
- 7 × 1000 = 7000 calories.
- Convert 50 kcal to calories:
- Multiply 50 by 1000.
- 50 × 1000 = 50000 calories.

Conversion Definitions
kcal: A kcal, or kilocalorie, is a unit of energy representing 1000 calories. It’s commonly used in food energy labeling to express the amount of energy food provides when eaten. The kcal is a larger scale unit to simplify numbers in nutrition.
calories: Calories are a measure of energy, often used in physics and nutrition. One calorie is the amount of heat needed to raise the temperature of 1 gram of water by 1 degree Celsius. In food, calories indicate how much energy the body can get from consuming the item.
Conversion FAQs
Why do we multiply kcal by 1000 to get calories?
The prefix “kilo” means 1000, so one kilocalorie equals 1000 calories. Multiplying by 1000 converts energy in kcal to the smaller calorie unit. This makes it straightforward to switch between these energy units without confusion.
Can calories be used interchangeably with kcal in food labels?
In many countries, food labels use kcal and calories interchangeably, since 1 kcal equals 1000 calories. However, usually when people say “calories” in nutrition, they mean kcal, not the smaller calorie unit. This can cause mix-ups if the units aren’t clarified.
Is a calorie the same as a calorie in physics?
There is a subtle difference. The calorie unit used in physics (small calorie) is the energy needed to heat 1 gram of water 1°C. The dietary calorie is actually a kilocalorie (kcal). So the term calorie in nutrition is a larger unit than the physics calorie.
How precise is the kcal to calorie conversion?
The conversion is exact since 1 kcal always equals 1000 calories. There is no rounding or estimation involved. The difference between kcal and calorie is purely a matter of scale, not measurement accuracy.
Why do nutrition labels mostly use kcal instead of calories?
Because the calorie values for food energy are generally large numbers, kcal simplifies the values making them easier to read and understand. Showing food energy in calories would produce very large numbers that are harder to interpret for consumers.
