What are Kilojoules and Calories?

Before we dive into the conversion process, let’s clarify what these units represent:

  • Kilojoule (kJ): The standard unit of energy in the International System of Units (SI).
  • Calorie (cal): A non-SI unit of energy, commonly used in nutrition.
  • Kilocalorie (kcal): Often referred to as “Calorie” (with a capital C) in nutrition contexts, equal to 1000 calories.

It’s important to note that when we talk about “calories” in food and nutrition, we’re actually referring to kilocalories (kcal).
