Formula
Item Calories = (Calories per 100g × Quantity in grams) / 100
Total Calories = Sum of all item calories
How it works
Total kcal = Σ (ingredient weight × kcal per 100g / 100) Example: Chicken Breast: 150g @ 165 kcal/100g = 247.5 kcal Rice: 200g @ 111 kcal/100g = 222 kcal Broccoli: 100g @ 34 kcal/100g = 34 kcal Total: 503.5 kcal Common Calorie Values (per 100g): Proteins: 165-250 kcal Vegetables: 20-90 kcal Grains: 100-400 kcal Oils/Fats: 700+ kcal Fruits: 40-90 kcal Unit Conversions: 1 oz = 28.35g 1 cup = 240mL (varies by food)
The food calorie calculator estimates total calories in your meal by summing calorie counts for each ingredient. Select foods, enter quantities in grams/oz/cups, and get total calories plus estimated macronutrients. Includes 30+ common foods and daily calorie reference percentages.
