What you can calculate here

The library covers everyday cooking and serious baking alike. Conversion tools move between cups, grams, ounces, and millilitres and handle butter, flour, and sugar by weight. Recipe tools scale servings up or down, convert pan sizes, and keep ratios intact. Baking tools work out bakers percentages, hydration, yeast quantities, and dough portions for bread and pizza. There are also temperature, time, and yield tools for roasting, frying, and batch cooking.

Who these calculators are for

Home cooks use them to halve a recipe or swap a pan without guesswork. Bakers use the percentage and hydration tools to dial in bread and pizza dough. Meal preppers scale batches to the right number of servings. Anyone who has ever stared at a recipe wondering how to double it will find the answer here.

Getting accurate results

A few habits make the results dependable:

  • Weigh ingredients where you can. Grams are far more accurate than cups for flour and sugar.
  • When scaling, remember that pan area, not just diameter, drives how much batter fits, and depth and bake time shift too.
  • For bread and pizza, hydration is the weight of water against the weight of flour, not a volume ratio.
  • Oven temperatures vary, so treat a converted temperature as a starting point and watch the food.

Frequently asked questions

Are these calculators free?

Yes. Every cooking and baking calculator here is free, with no account and no usage limit.

Do they handle both volume and weight?

Yes. Most conversion tools switch between cups, grams, and ounces, and several let you toggle units to suit your recipe.

How accurate are the results?

Conversions use standard ingredient densities and are accurate for typical ingredients. Weighing is always more precise than measuring by volume.

Will they work on my phone?

Yes. Every tool is responsive and works the same on phone, tablet, and desktop, handy when your hands are floury.

Which calculator should I start with?

Pick your task: resizing a recipe, converting a measurement, or working out dough. Each tool links to related ones.

Do you store the numbers I enter?

No. Everything is calculated in your browser, and your inputs are not saved or sent anywhere.
