Enter the amount of protein, carbohydrates, and fats into the calculator to determine the total caloric content.

Grams To Calories Formula

The following formula is used to calculate the total caloric content of food.

TC = (P * 4) + (C * 4) + (F * 9)


  • TC is the total caloric content (calories)
  • P is the amount of protein (grams)
  • C is the amount of carbohydrates (grams)
  • F is the amount of fats (grams)

To calculate the total caloric content, multiply the amount of protein by 4, the amount of carbohydrates by 4, and the amount of fats by 9. Then, add all these results together.

What is Grams To Calories?

Grams to calories is a conversion used in nutrition to determine the caloric content of food. Each macronutrient (protein, carbohydrates, and fats) has a specific caloric value per gram. Proteins and carbohydrates both contain 4 calories per gram, while fats contain 9 calories per gram. Therefore, by knowing the grams of each macronutrient in a food item, you can calculate the total caloric content. This conversion is crucial in dietary planning and tracking.

How to Calculate Grams To Calories?

The following steps outline how to calculate the Grams To Calories using the given formula:

  1. First, determine the amount of protein (P) in grams.
  2. Next, determine the amount of carbohydrates (C) in grams.
  3. Next, determine the amount of fats (F) in grams.
  4. Use the formula: TC = (P * 4) + (C * 4) + (F * 9) to calculate the total caloric content (TC) in calories.
  5. Finally, calculate the Grams To Calories.
  6. After inserting the values of P, C, and F into the formula and calculating the result, check your answer with a calculator.

Example Problem:

Use the following variables as an example problem to test your knowledge:

Amount of protein (P) in grams = 20

Amount of carbohydrates (C) in grams = 30

Amount of fats (F) in grams = 10
