Cooking & Kitchen tools
Ratios, conversions, and timing for coffee, bread, pizza dough, roasts, cocktails, and whole recipes.
Find a dough's hydration percentage from flour and water, or the water needed for a target hydration, with optional starter accounting.
Convert a cake recipe between round, square, sheet, loaf, and bundt pans with an ingredient scale factor and bake-time guidance.
See how stirring or shaking changes a cocktail's volume and ABV, and how much water to pre-add when batching drinks for a bottle.
Work out how much coffee and water to use for pour-over, french press, drip, espresso, cold brew, or AeroPress, with editable ratios and grind hints.
Convert cups, tablespoons, and teaspoons to grams (and back) for flour, sugar, butter, and 60+ ingredients, with US, metric, and UK cup sizes.
Estimate roasting time for turkey, chicken, beef, pork, ham, or lamb from weight and doneness, with USDA-safe internal temperatures and rest times.
Turn a ball count, ball weight, and baker's percentages for hydration, salt, and yeast into exact flour, water, salt, and yeast weights.
Paste an ingredient list and scale it by servings, by a factor, or by the amount of one ingredient you have, with tidy fractions and optional metric.
Get the right amount of water and a rough cook time for white, jasmine, basmati, brown, sushi, or arborio rice, in cups or grams.
Plan a sourdough bake from flour or dough weight and hydration, correctly subtracting the flour and water your starter already contains.
Find how long a frozen turkey takes to thaw in the fridge or cold water, and exactly when to start so it's ready for the meal.
Convert between instant, active dry, and fresh yeast in grams and teaspoons, showing all three equivalents at once.
About Cooking & Kitchen tools
Kitchen math, done properly. The ratio calculators cover coffee brewing (pour-over, French press, drip, espresso, cold brew, and AeroPress, each with editable ratios and grind hints) and rice varieties from jasmine to arborio. The baking tools work in baker's percentages the way serious recipes do: the pizza dough calculator turns ball count, ball weight, and hydration into exact flour, water, salt, and yeast weights, and the sourdough calculator correctly subtracts the flour and water your starter already contains — the step most home bakers miss.
The timing tools answer high-stakes holiday questions: how many days a frozen turkey needs in the fridge (and when to start so it's ready for the meal), and roast times for turkey, chicken, beef, pork, ham, or lamb by weight and doneness, with USDA-safe internal temperatures and rest times. Converters handle the recipe-adaptation chores — resizing a whole ingredient list by servings into amounts you can actually measure, turning cups and spoons into grams for some sixty ingredients, scaling a cake between pan shapes and sizes with bake-time guidance, and converting between instant, active dry, and fresh yeast.
The cocktail dilution calculator is for anyone batching drinks: it models how stirring or shaking changes volume and ABV, and how much water to pre-add when bottling. Everything runs free in your browser — no accounts, no apps, and the pages keep working with flour on your hands and spotty kitchen Wi-Fi.
