Article: Calories and How to Calculate Them for Proper Nutrition


Calories are used as a unit of measurement for energy in the field of nutrition and dietetics. However, there is sometimes a need to convert these calories into other units such as joules and kilojoules. In this article, we will discuss how to convert calories to joules and kilojoules and provide a conversion table to help you do so.

What Are Calories, Joules, and Kilojoules?

  • Calories: Calories are a common unit of energy measurement in nutrition. They are used to measure the amount of energy consumed or contained in food and beverages. Calories are abbreviated as "cal."
  • Joules: Joules are an international unit for measuring energy. They are widely used in science and engineering. 1 joule is approximately equal to 0.239 calories.
  • Kilojoules: Kilojoules are a unit of energy measurement also used extensively. 1 kilojoule is equal to 239 calories.

How to Convert Calories to Joules:


To convert calories to joules, you can use the following relationship: 1 calorie (Calorie) = 4.184 joules (Joule) Simply multiply the number of calories by 4.184 to get the joules. For example, if a meal contains 100 calories, it is equivalent to 418.4 joules.

How to Convert Calories to Kilojoules:


To convert calories to kilojoules, you can use the following relationship: 1 calorie (Calorie) = 0.004184 kilojoules (Kilojoule) Simply divide the number of calories by 239 to get the kilojoules. For example, if a meal contains 100 calories, it is equivalent to 0.4184 kilojoules.
