Recipe Fraction Scaler
Scale a recipe up or down with exact fractions. Keep each ingredient and unit beside its new amount.
Does scaling change the ingredient unit?
No. Enter quantity, unit, and ingredient columns, then choose original and target servings. The tool multiplies each quantity by the exact serving ratio and retains the original unit and ingredient label.
