Conversion Formula
The conversion from kilocalories to calories use a simple multiplication formula. Since 1 kilocalorie equals 1000 calories, you multiply the number of kcal by 1000 to get the value in calories.
Formula:
calories (cal) = kilocalories (kcal) × 1000
This works because “kilo” means one thousand, so every kilocalorie contains 1000 calories. For example, to convert 45 kcal to cal:
- Start with 45 kcal.
- Multiply 45 by 1000.
- 45 × 1000 = 45000 cal.
Conversion Example
- Convert 12 kcal to cal:
- 12 kcal × 1000 = 12000 cal.
- Simply multiply 12 with 1000.
- Convert 30.5 kcal to cal:
- 30.5 × 1000 = 30500 cal.
- Multiply decimal value directly by 1000.
- Convert 67 kcal to cal:
- 67 × 1000 = 67000 cal.
- Multiply whole number by 1000.
- Convert 23.75 kcal to cal:
- 23.75 × 1000 = 23750 cal.
- Decimal multiplication works same way.
- Convert 50 kcal to cal:
- 50 × 1000 = 50000 cal.
- Multiply value by 1000 as usual.

Conversion Definitions
kcal (kilocalorie): A unit of energy equals to 1000 calories, commonly used to measure food energy content. Kilocalories represent the energy needed to raise the temperature of 1 kilogram of water by 1 degree Celsius. It is a standard dietary energy measure worldwide.
cal (calorie): The calorie is a smaller unit of energy representing heat, defined as the amount of heat required to raise the temperature of 1 gram of water by 1 degree Celsius. It is mostly used in chemistry and physics, and 1000 cal make 1 kcal.
Conversion FAQs
Why multiply kcal by 1000 to get calories?
Because kilocalorie means 1000 calories, multiplying by 1000 converts the larger unit to the smaller, more precise unit. It aligns with metric prefixes where “kilo” means thousand, making the math straightforward.
Can I convert calories to kcal using division?
Yes, to go from calories to kilocalories, divide the calorie value by 1000. For example, 45000 cal ÷ 1000 = 45 kcal. This reverses the multiplication used in the opposite conversion.
Is the calorie in kcal same as food calorie?
The term “calorie” on food labels usually means kilocalorie (kcal). So, when you see 45 “calories” on food, it often means 45 kcal or 45000 actual calories in scientific terms.
Does this conversion apply to all kinds of calories?
The conversion applies only to thermochemical calories related to energy in food and heat. Some scientific fields use different calorie definitions, but for food energy, 1 kcal equals 1000 cal.
Why are kcal preferred over cal in nutrition?
Because calories for food energy usually are large numbers, kcal simplifies representation by scaling the value down by 1000, making it easier to understand and communicate nutrition facts.
