90 kcal equals 90,000 cal.
The conversion from kilocalories (kcal) to calories (cal) involves multiplying the number of kilocalories by 1,000, since 1 kcal equals 1,000 cal. Therefore, 90 kcal is converted by multiplying 90 by 1,000, resulting in 90,000 cal.

Conversion Formula
To convert kilocalories (kcal) into calories (cal), you multiply the kcal value by 1,000. This conversion works because one kilocalorie is equal to one thousand calories. The prefix “kilo-” means one thousand, which is why we multiply by 1000.
Formula:
cal = kcal × 1000
Example: Converting 90 kcal to cal
- Start with the value in kcal: 90 kcal
- Multiply by 1000: 90 × 1000 = 90,000
- Result is 90,000 cal
Conversion Example
- Example 1: 45 kcal to cal
- Take 45 kcal
- Multiply by 1000: 45 × 1000 = 45,000
- The result is 45,000 cal
- Example 2: 120.5 kcal to cal
- Start with 120.5 kcal
- Multiply by 1000: 120.5 × 1000 = 120,500
- Answer: 120,500 cal
- Example 3: 78 kcal to cal
- Given 78 kcal
- Multiply by 1000: 78 × 1000 = 78,000
- Converted value is 78,000 cal
- Example 4: 99.9 kcal to cal
- Value is 99.9 kcal
- Multiply by 1000: 99.9 × 1000 = 99,900
- So, 99,900 cal

Conversion Definitions
kcal: Kilocalorie, often called a “Calorie” in food energy contexts, measures energy equal to 1,000 calories. It quantifies the amount of heat needed to raise the temperature of 1 kilogram of water by 1 degree Celsius, widely used in nutrition to describe food energy content.
cal: The calorie is a unit measuring energy, specifically heat energy. One calorie is the energy needed to increase the temperature of 1 gram of water by 1 degree Celsius. This smaller unit is used in physics and chemistry but less common than the kilocalorie in nutrition.
Conversion FAQs
Why does 1 kcal equal 1000 cal?
Because kilo means thousand, the kilocalorie is exactly 1,000 times the calorie. This comes from the metric system prefixes, where kilo always multiplies the base unit by 1,000. So, 1 kcal is 1,000 cal by definition.
Is kcal the same as the Calorie listed on food packages?
Yes, in nutrition, the Calorie with a capital C equals 1 kilocalorie (kcal). So when a label says 90 Calories, it means 90 kcal, which equals 90,000 cal. This usage can be confusing because the lowercase calorie is much smaller.
Can I convert calories back to kcal easily?
Yes, to convert cal to kcal, divide the calorie value by 1,000. For example, 90,000 cal ÷ 1,000 = 90 kcal. This reverse operation uses the same metric relationship between units.
Why are calories used in food while physics uses joules?
Calories, especially kilocalories, have been traditional in nutrition for measuring energy in food. Physics prefers joules because it’s the SI unit for energy, making it standard for scientific work. Both measure energy but in different systems.
Does converting kcal to cal affect nutritional information accuracy?
Not really, converting units doesn’t change the actual energy content, just the unit scale. However, cal are less practical for food labels since values become large and less readable, so kcal is preferred for clarity.
