Guide to Cooking Calculators

This hub gathers the everyday maths that home cooks, keen bakers and people planning gatherings tend to hit mid-task: scaling a recipe up or down, moving between cups and grams, resizing a bake to a different tin, or working out how much food to buy for a crowd. The tricky part is that "a cup" is not a fixed weight, ingredients differ (a cup of flour and a cup of sugar are not the same mass), and roasting and bread rely on ratios rather than single numbers, so the right tool depends on what you already know versus what you are trying to find.

Measuring and converting ingredients

Reach for cups-to-grams or grams-to-cups when a recipe uses one unit and your scales or measuring cups use the other; use the pan converter when your tin differs from the one specified so you can adjust batter depth and timing.

Scaling recipes and portions

Use the recipe scaler to change the number of servings while keeping ingredient proportions correct, and the catering portion calculator when you need quantities per head for a larger group rather than a fixed recipe.

Ratio-based cooking and bread

These work from ratios rather than fixed amounts: dough hydration and the sourdough calculator balance flour, water and starter, while the coffee ratio tool sets brew strength and the roast timer estimates cooking time from weight.
