Macro Calorie Converter

Macro Calorie Converter

This converter turns grams of each macronutrient into calories and shows the percentage split of your intake. Protein and carbohydrates each supply 4 calories per gram while fat supplies 9, so the same weight of fat carries more than twice the energy. Enter the grams of protein, carbohydrates and fat from a meal or a whole day to see total calories and how the energy is divided — useful for checking a label or planning a macro ratio.

Energy values: protein and carbohydrates provide 4 kcal per gram, fat provides 9 kcal per gram. Fiber and the exact protein value vary slightly by source, so labels may differ a little.
