Calculating the Percentage Value for an Ingredient

To determine the percentage value for each ingredient in a formula, first, all of the ingredients must be in units measured by weight, not volume. Second, they must all be in the same unit of weight. For example, all ounces or all pounds—you cannot work with ingredients that are in both ounces and pounds. Simply divide the weight of the ingredient by the weight of the flour and then multiply the result by 100.

When making any calculations, numerical values must be expressed in the same unit of measure (e.g., pounds, ounces, grams, kilograms); if necessary, convert any values before beginning the calculation.
