90 kcal equals 90,000 calories.
The kilocalorie (kcal) is often used in food energy measurements, and 1 kcal equals 1,000 calories (small ‘c’). Therefore, converting 90 kcal to calories means multiplying by 1,000.

Conversion Formula
The formula to convert kilocalories (kcal) to calories is:
calories = kcal × 1000
This works because 1 kilocalorie is exactly equal to 1,000 calories. The kilocalorie is a larger unit of energy, commonly used in nutrition, while calorie (small ‘c’) is a smaller unit.
Example calculation:
- Start with 90 kcal
- Multiply by 1,000 (since 1 kcal = 1,000 calories)
- 90 × 1,000 = 90,000 calories
Conversion Example
- Convert 50 kcal to calories:
- 50 × 1000 = 50,000 calories
- Each kcal has 1,000 calories; multiply accordingly.
- Convert 120 kcal to calories:
- 120 × 1000 = 120,000 calories
- Simply multiplying by 1,000 converts kcal to calories.
- Convert 75.5 kcal to calories:
- 75.5 × 1000 = 75,500 calories
- Decimal values are handled the same way by multiplication.
- Convert 100 kcal to calories:
- 100 × 1000 = 100,000 calories
- Easy to calculate since 100 × 1,000 is 100,000.

Conversion Definitions
kcal: A kilocalorie, often called a “Calorie” with a capital C on food labels, is a unit of energy equal to 1,000 small calories. It measures the amount of heat needed to raise the temperature of 1 kilogram of water by 1 degree Celsius. This unit is used in nutrition to express energy content in food.
calories: The calorie (small ‘c’) is a unit of energy that equals the amount of heat needed to raise 1 gram of water by 1 degree Celsius. It is smaller than a kilocalorie and mostly used in scientific contexts. In food, calories usually refer to kilocalories but written with a capital “C”.
Conversion FAQs
Why does 1 kcal equal 1,000 calories?
The difference comes from the size of the unit measured. A calorie (small ‘c’) is the energy to heat 1 gram of water by 1°C, while a kilocalorie (kcal) measures the energy to heat 1 kilogram of water by 1°C. Since 1 kg equals 1,000 grams, 1 kcal equals 1,000 calories.
Can I use kcal and calories interchangeably when counting food energy?
In nutrition, kcal and Calories (capital C) are generally used interchangeably because 1 Calorie equals 1 kcal. However, when precision matters, kcal means 1,000 small calories, while calorie (lowercase) is a smaller unit. On food labels, “Calories” means kcal.
What happens if I confuse kcal with calories in calorie counting?
Confusing kcal with small calories can cause a 1,000-fold error. For example, 90 kcal is 90,000 calories. Using the smaller unit instead of kcal would greatly misrepresent energy intake, affecting diet or science calculations.
Is the conversion factor always 1,000 for kcal to calories?
Yes, the conversion factor is constant because it depends on the definition of the units. One kilocalorie always equals 1,000 calories, regardless of context or substance.
Why do some sources use Calories with capital C instead of kcal?
Calories with a capital “C” are synonymous with kilocalories in food energy. This notation simplifies dietary information but can confuse those expecting the scientific calorie unit. Both terms represent the same amount of energy: 1,000 small calories.
