The Science Behind the Calculator (Formula Explanation)

This calculator uses standard nutritional science values to convert macronutrients into calories.

Protein Calories Formula

Protein Calories=Protein (g)×4Protein\ Calories = Protein\ (g) \times 4Protein Calories=Protein (g)×4

Protein provides 4 calories per gram.


Carbohydrate Calories Formula

Carbohydrate Calories=Carbs (g)×4Carbohydrate\ Calories = Carbs\ (g) \times 4Carbohydrate Calories=Carbs (g)×4

Carbohydrates also provide 4 calories per gram.


Fat Calories Formula

Fat Calories=Fat (g)×9Fat\ Calories = Fat\ (g) \times 9Fat Calories=Fat (g)×9

Fats are more calorie-dense, providing 9 calories per gram.


Total Calories Formula

Total Calories=Protein Calories+Carbohydrate Calories+Fat CaloriesTotal\ Calories = Protein\ Calories + Carbohydrate\ Calories + Fat\ CaloriesTotal Calories=Protein Calories+Carbohydrate Calories+Fat Calories

Example Calculation

Let’s understand how the calculator works with a real example.

Daily Intake:

  • Protein: 120 grams
  • Carbohydrates: 200 grams
  • Fats: 70 grams

Step 1: Protein Calories

120 × 4 = 480 kcal

Step 2: Carbohydrate Calories

200 × 4 = 800 kcal

Step 3: Fat Calories

70 × 9 = 630 kcal


Step 4: Total Calories

480 + 800 + 630 = 1910 kcal


Final Output:

  • Protein Calories: 480 kcal
  • Carb Calories: 800 kcal
  • Fat Calories: 630 kcal
  • Total Calories: 1910 kcal
