How this calculator works
The serving size converter applies a simple scaling ratio: desired servings divided by original servings. Every ingredient quantity is multiplied by that same ratio so proportions stay balanced. This keeps flavor, texture, and hydration close to the original recipe while helping you avoid guesswork.
The tool supports manual ingredient entry and recipe-prefilled data from recipe pages. Smart rounding keeps practical kitchen measurements and optional fraction formatting makes outputs easier to read for home cooks who prefer 1/2 or 3/4 style measurements.
For best results, scale by weight where possible. Volume measurements can still be used, but grams provide better consistency. Use the share link feature to save a specific scale scenario and send it to family members, clients, or kitchen staff.

FAQ
Can I show fractions instead of decimals?
Yes. Toggle fraction display to format outputs like 1/2, 2/3, and 3/4 where possible.
Does scaling also change cooking time?
Not always. Use the cooking time adjuster tool to estimate timing and temperature updates.
