Input Parameters

This is the energy content of the food per gram (e.g., 4 for carbohydrates, 9 for fats)

Calculation Results

Calculation Formula

Calories = Weight (grams) × Calories per gram

Where:
Weight (grams) = The weight of the food in grams
Calories per gram = The energy content of the food per gram

Learn how to use the Grams to Calories Converter calculator and its working principles

How to Use the Calculator

  1. Enter the weight of the food in grams in the "Weight (grams)" field.
  2. Enter the calories per gram of the food in the "Calories per gram" field.

    Common values:

    • Carbohydrates: 4 calories per gram
    • Fats: 9 calories per gram
    • Proteins: 4 calories per gram
  3. Click the "Calculate" button to compute the total calories.
  4. The result will be displayed in the "Total Calories" field.
  5. Click "Reset" to clear all inputs and start over.

Working Principle

The calculator uses a simple formula to calculate the total calories:

Calories = Weight (grams) × Calories per gram

This formula assumes that the entire weight of the food is made up of the substance with the specified calories per gram. For example, if you have 100 grams of carbohydrates (4 calories per gram), the calculator will show 400 calories.

Example

Suppose you have 150 grams of nuts, which contain approximately 9 calories per gram:

  1. Enter 150 in the "Weight (grams)" field.
  2. Enter 9 in the "Calories per gram" field.
  3. Click "Calculate".
  4. The result will be 1350 calories.

Limitations

This calculator provides a basic estimation of calorie content based on weight and calories per gram. It does not account for different food compositions or cooking methods that might affect the actual calorie content.
