Calculation breakdown
- Scaled quantity
- original quantity × (target servings ÷ original servings)
Worked example
200g of flour for 4 servings scaled to 6 servings becomes 200 × (6÷4) = 300g.
Assumptions
- Applies the same multiplier to all ingredients; cooking time doesn't scale the same way.
How this calculator works
Enter an ingredient quantity from your original recipe along with its original and target servings to calculate the scaled amount needed.
Frequently asked questions
Does this work for any unit of measurement?
Yes, the scaling factor applies to any unit — grams, cups, millilitres or tablespoons — just apply the same multiplier to every ingredient.
What if I'm scaling down to less than one serving?
Enter your target as a decimal, such as 0.5 servings, and the calculator will scale accordingly.
Does cooking time scale the same way?
No, cooking time doesn't scale linearly with quantity — this calculator is for ingredient amounts only.
