Recipes Calculator is a free collection of baking and kitchen tools. We build calculators that help home bakers scale recipes accurately, convert between pan sizes, calculate baker’s percentages, and find ingredient substitutions when supplies run low.
Why we built this
Baking is part science and part art, but the math does not have to be hard. Too many recipes fail because of simple conversion mistakes — a cup of flour that weighs too much, a pan that is too small, or a dough scaled incorrectly. We wanted a clean, fast place where anyone can get the numbers right.
Privacy first
All calculations happen in your browser. We do not store your recipes, track your usage, or require an account. The only thing we save is your dark-mode preference in localStorage.
How we calculate
Our recipe scaler uses standard ingredient density data to convert volume measurements to gram weights. Pan size conversions are based on geometric area. Baker’s percentages follow the professional convention where flour is always 100%. Every tool is designed to be simple, accurate, and transparent.
Recommended baking tools
A digital kitchen scale is the most important tool for consistent baking. We also recommend quality pans, an oven thermometer, and a good bench scraper. Browse digital kitchen scales or King Arthur Baking supplies for trusted options.
