How to use the Recipe Scaler
Quantities at the start of each line are detected automatically — whole numbers, decimals, fractions (¾ written as 3/4) and mixed numbers (1 1/2). When scaling baking recipes by large factors, adjust pan size and baking time too.
Formula
Scale factor = New servings ÷ Original servings. Every leading quantity is multiplied by this factor and rounded to the nearest ⅛ for small amounts.
