Frequently Asked Questions
Are kcal and calories the same thing?
In nutrition and food labeling, yes! When food labels say "calories," they actually mean kilocalories (kcal). One kilocalorie equals 1,000 small calories. The confusion comes from the fact that the food industry uses "Calories" (with a capital C) to mean kilocalories.
Why are there two different units?
The small calorie (cal) is the amount of energy needed to raise 1 gram of water by 1°C. The kilocalorie (kcal) is 1,000 times larger and is more practical for measuring food energy. Over time, "Calorie" became shorthand for kilocalorie in nutrition.
Which unit should I use for tracking food?
For food tracking, use kilocalories (kcal) or Calories (with capital C) - they're the same. Most food labels and nutrition apps use these terms interchangeably. The small calorie (cal) is rarely used in nutrition.
How do I convert kcal to calories?
To convert kilocalories to small calories, multiply by 1,000. For example, 100 kcal = 100,000 cal. However, in nutrition contexts, 100 kcal = 100 Calories (food calories).
What about kilojoules (kJ)?
Kilojoules are another energy unit used in some countries. To convert: 1 kcal = 4.184 kJ. Many food labels show both kcal and kJ values.
