Scale an ingredient from the original number of servings to the amount you want to make. Repeat for every ingredient.
The working, clearly explained
Enter decimal quantities: for example, 0.5 for ½ and 1.25 for 1¼. The result keeps whatever unit your ingredient uses: cups stay cups, grams stay grams. This tool does not convert volume to weight or account for ingredient density. Seasoning, pan size and cooking time need your judgment.
A recipe serving four uses 2 cups of flour. For six servings, the factor is 1.5 and the scaled amount is 3 cups.
A recipe serving eight uses 3 eggs. For four servings, the factor is 0.5 and the scaled amount is 1.5 eggs. Beat an egg and portion it as appropriate for your recipe.
No. Time depends on thickness, pan size, equipment and the food. Follow a suitable recipe and check doneness.
The arithmetic factor is the same, but seasonings and leavening may need adjustment, especially for large batches.
