Scale a recipe without losing the ratio
Enter the original servings, the new servings, and up to five ingredient amounts. The tool multiplies each amount by the same factor. It will not tell you how to split a single egg in a halved cake. That is still your call. This is arithmetic, not a test of baking chemistry.

Common questions
How does the recipe scaler work?
It divides the new serving count by the original serving count and multiplies each ingredient amount by that factor.
Can it tell me how to halve a single egg?
No. Uneven units such as one egg still need your judgment. The tool only multiplies the numbers you enter.
Does scaling change safe cooking temperatures?
No. Safe internal temperatures stay the same. Use the turkey, ham, or prime rib pages for official USDA temperatures.
Is this an official serving standard?
No. It is only arithmetic on the amounts you type.
