Accurate, free kitchen calculators built for home cooks who use modern appliances.
KitchenCalc was created to solve a simple problem: modern kitchens are full of specialized appliances, but recipes are still written for conventional ovens and stovetops. We built a suite of free, accurate calculators that convert times, temperatures, and ratios for air fryers, Instant Pots, rice cookers, sous vide machines, slow cookers, bread machines, and microwaves.
All calculations run entirely in your browser. We do not collect personal data, require signups, or hide features behind paywalls.
Our formulas are derived from manufacturer guidelines, food safety standards (USDA, FDA), and established culinary references:
