Cooking & Food Safety Calculators
Free kitchen calculators built on USDA guidelines: turkey cooking time by weight with a thaw-and-roast schedule, and an is-my-food-still-safe checker for leftovers and food left out.
Charts tell you the rule; these calculators work it out for your food, your weight, and your schedule. Every calculator uses the same USDA guidelines as the rest of the site, and every temperature switches between °F and °C with the toggle at the top of the page.
