Yield factor formula

• A. yield factor = original yield / desired yield
• B. yield factor = desired yield / original yield
• C. yield factor = desired yield + original yield
• D. yield factor = sqrt(desired yield * original yield)

Answer: (B)

In scaling recipes, the yield factor is the ratio of what you want to produce to what the recipe originally yields. This tells you exactly how many times to multiply every ingredient to keep the proportions the same. The correct formula is yield factor = desired yield ÷ original yield. If you need more servings, the factor is greater than 1; if you need fewer, it’s less than 1. For example, a recipe that yields 12 cookies, but you want 24, factor = 24/12 = 2, so you double every ingredient. If you only need 6 cookies, factor = 6/12 = 0.5, so you halve each ingredient. The other options either invert the relationship, add quantities, or don’t preserve proportions, which is not suitable for scaling.
