Recipe Nutrition Calculator
This tool totals a recipe's calories and macros from figures you enter and divides them by the servings. It holds no food composition table, so it cannot be told two cups of flour and look up what that contains: each ingredient line is calories, protein, carbohydrate and fat taken off a label for the amount the recipe uses. In return it does the arithmetic that goes wrong by hand, giving the totals, the per serving and per 100 gram figures, the share of calories from each macro, and a check of the calories you entered against the 4, 4 and 9 kcal per gram the macros come to. A gap of a few percent there is label rounding, and a wide one usually means a digit slipped.
