Scale recipe ingredients up or down when changing serving size, batch size, or meal-prep portions.
| Ingredient | Original | Adjusted |
|---|---|---|
| Flour | 2 cup | 4 cup |
| Sugar | 0.5 cup | 1 cup |
Scaling factor = desired servings ÷ original servings. Adjusted quantity = original quantity × scaling factor.
Result: Scaling factor: 2.5. Two cups become five cups.
Enter the recipe, ingredient, or measurement values requested above, then select the matching units or options. The calculator keeps the calculation close to the top of the page and shows the method below so you can review the assumptions before using the result.
Set the original servings to the recipe servings and the desired servings to twice that amount. Every ingredient is multiplied by 2.
Yes. The calculator uses 5 ÷ 8 = 0.625 as the scaling factor and multiplies every ingredient by that number.
Not automatically. Ingredient quantities scale mathematically, but cooking time depends on pan size, thickness, temperature, and doneness.
Round practical kitchen amounts gently. For baking, weigh ingredients when precision matters.
