Cooking Calculators

To scale a recipe, multiply every ingredient by (new servings ÷ original servings) — simple in theory, tedious in practice when a dish has fifteen items and you're tripling it for a dinner party. The recipe scaler handles that arithmetic instantly, so you spend time cooking instead of doing mental division at the counter.

The 4 tools here cover the questions that trip people up most often. Unit conversion is the biggest one: a US recipe calls for cups, a UK recipe calls for grams, and the two systems don't map cleanly because density varies by ingredient. The cooking converter accounts for that. Feeding a crowd adds another layer — plan roughly ½ pound (about 225 g) of boneless meat per adult, but the meat calculator adjusts that figure for bone-in cuts and different appetites so you don't over- or under-buy.

Baking is the one area where eyeballing fails. Flour-to-fat-to-liquid ratios determine texture, and small deviations compound across a full batch. Get the ratios right first, then scale — not the other way around. Pick a tool below; popular ones appear first.
