How to Convert Grams of Fat, Protein, and Carbohydrates to Calories – Online Grams to Calories Converter

Fats, proteins and carbohydrates are macronutrients and thus provide energy. Energy is measured in calories. The amount of energy in 1 gram differs between macronutrients:

  • Fat has 9 calories per gram.
  • Protein has 4 calories per gram.
  • Carbohydrates have 4 calories per gram.
    Carbohydrates may partially consist of Dietary Fiber. Dietary fiber can not be digested and thus should be subtracted from the total Carbohydrates.

The formula:

(Fat x 9) + (Protein x 4) + ( (CarbohydratesDietary Fiber) * 4) = Total Calories
