Frequently Asked Questions

Recipe scaling multiplies each ingredient amount by the ratio of your desired servings to the original servings. For example, if a recipe serves 4 and you want 6, each ingredient is multiplied by 1.5 (6 ÷ 4). This ensures every proportion stays balanced so the dish tastes exactly the same.
Yes! You can enter amounts as decimals (0.5, 0.75), as common fractions typed with a slash (1/2, 3/4), or as Unicode fraction symbols (½, ¾). The scaler handles all of these formats and rounds the result to clean, easy-to-measure numbers.
Scaling changes ingredient quantities, but baking times don't scale linearly. A doubled batch in a larger pan may need 10–20% more time, while individual portions like cookies stay about the same. Always check for doneness early. Try our Cooking Time Converter for temperature and time adjustments.
