Recipe scaling guide
This free recipe converter calculator works as a recipe divider, recipe multiplier, ingredient calculator and recipe serving calculator. It changes quantities by the serving ratio while leaving each ingredient in its original unit.
The scale factor is 4 ÷ 8 = 0.5.
The scale factor is 6 ÷ 4 = 1.5.
Use the calculator for family dinners, baking batches, meal prep or smaller portions. Fractions such as 1/2 and 1 1/2 are accepted. For measurement changes rather than serving changes, keep in mind that a cooking measurement converter should only convert compatible units; volume-to-weight conversions need ingredient-specific information.
Scaling more than one recipe? Use the free grocery list generator for multiple recipes to combine matching ingredients into one aisle-grouped shopping list.

Yes. Choose a smaller new serving count to divide a recipe. For example, changing eight servings to four halves every ingredient quantity.
Yes. Choose a larger serving count and the recipe multiplier increases each recognised quantity while preserving familiar fractions where practical.
No. Cups measure volume and grams measure weight, so a safe conversion depends on the ingredient's density. SavourWeek scales quantities but does not guess unsafe cross-unit conversions.
Yes. Import a public recipe webpage, paste text, or upload a supported document or photo. Review the ingredients and cooking method, scale it, then print the complete recipe.
