Reference & details

How it works

Scale one recipe ingredient

Enter the original and target serving counts, then one ingredient’s weight. Repeat for the other ingredients using the same serving counts.

Scaled grams = original grams × target servings ÷ original servings

Read the result with its conditions

Cooking, cooling, setting time and equipment capacity do not scale by this factor. For preserved foods, follow a tested recipe’s permitted batch size and processing instructions. Measure the finished batch to check its actual yield.

Updated: September 2026

Example Scenarios

Change 4 servings to 12 and enter 250 g original ingredient weight.

→ 750 g at a scale factor of 3. Repeat for the other recipe ingredients.

Common Mistakes to Avoid

Multiplying cooking or preservation times

The factor scales ingredient mass. Follow the recipe’s process, equipment and permitted batch-size instructions separately.

FAQ

Yes. Fractional servings and gram amounts are retained in the calculation. Round only to a precision your scale can measure.

It scales one ingredient at a time. Apply the same factor to each permitted ingredient; use the original recipe’s method and batch-size guidance.
