Recipe scaler
Adjust ingredient quantities when cooking for a different number of people.
Up to 50 ingredients. Quantity examples: 200, 1/2, 1 1/2 or ½. Servings: greater than 0, at most 1000. Scaling factor: 0.001–1000. No unit conversion.

How it works
Enter the original and new servings, then each ingredient’s quantity, unit and name. Scaling a four-person recipe to seven people multiplies each amount by 1.75: 200 g flour becomes 350 g, and 1/2 cup becomes 0.875 cup.
Good to know
Will cooking time and every ingredient scale perfectly?
The tool only multiplies quantities. It does not convert cups to grams, infer density, adjust cooking time or change oven temperatures. Salt, spices and leavening may need manual adjustment; eggs may need weighing or rounding. Results use up to six decimal places, so keep practical kitchen measurements in mind.
