Cooking & Kitchen Converters
Follow any recipe from anywhere, convert grams to cups for real ingredients, switch between °F, °C and gas marks, scale a recipe to any number of servings, and check safe meat temperatures. Weights and temperatures are from trusted sources (King Arthur Baking, USDA, NIST), and every tool runs entirely in your browser.
- Grams to Cups Converter Pick an ingredient and convert between cups, tablespoons, grams and ounces, using the correct weight for that ingredient, not a one-size-fits-all number.
- Cooking Measurement Converter Convert any cooking volume between US, metric and imperial units, and see all the equivalents at once, so a recipe from anywhere is easy to follow.
- Butter Converter (Sticks, Cups, Grams) Convert butter between sticks, tablespoons, cups, grams and ounces instantly, perfect for bridging American stick-based recipes and the rest of the world’s grams.
- Oven Temperature Converter (°F, °C, Gas Mark) Convert an oven temperature between °Fahrenheit, °Celsius and gas mark, and get the fan-oven setting, so a recipe written for any oven works on yours.
- Recipe Scaler & Multiplier Enter your recipe’s ingredients and change the servings
- Baking Pan Size Converter Compare the pan your recipe calls for with the pan you have, and get the batter ratio, so you can swap a round tin for a square one, or resize, with confidence.
- Baker's Percentage Calculator Enter your flour and the other ingredients by weight, and get each one as a baker's percentage plus the dough hydration, the language of every serious bread recipe.
- Yeast Converter (Active Dry, Instant, Fresh) Convert a yeast quantity between active dry, instant and fresh
- Coffee-to-Water Ratio Calculator Set your coffee-to-water ratio and enter either the coffee or the water you have, and get the exact amount of the other, for consistent coffee, cup after cup.
- Meat Cooking Temperature Guide The safe internal temperatures to cook meat, poultry, fish and eggs to, straight from USDA FoodSafety.gov, plus a cook’s doneness guide for steaks.
- Brine Calculator (Salt Ratio) Enter the water amount and a target salt percentage to get the exact salt
- Air Fryer Conversion Calculator Enter the oven temperature and time from your recipe to get the air-fryer temperature and time.
- Roast Cooking Time Calculator Enter the weight and choose the meat to estimate the roasting time, with the safe internal temperature to cook to.
- Slow Cooker Conversion Calculator Enter your recipe's normal cooking time to get the equivalent slow-cooker time on Low and High.
- Rice to Water Ratio Calculator Choose your rice type and amount to get the right water quantity, the cooked yield and the simmer time.
- Turkey Cooking Time Calculator Roast a turkey at 325°F for about 13 minutes per pound unstuffed
- Sourdough Starter Calculator Feed a sourdough starter at a ratio of starter : flour : water, so 30 g of starter at 1:2:2 needs 60 g flour and 60 g water.
- Party Food & Drink Calculator Party quantities scale with guests and hours, plan on roughly 6 oz of cooked main protein per person, about one drink per person per hour, and 1-1.5 lb of ice each.
Frequently asked questions
Are these cooking conversions accurate?
Yes. Volume conversions use exact NIST/BIPM factors, ingredient weights come from King Arthur Baking’s Ingredient Weight Chart (the US baking standard), oven temperatures follow the standard UK cooking table, and meat temperatures are the USDA/FoodSafety.gov safe minimums. Sources are cited on each tool.
Why does a cup of flour weigh differently than a cup of sugar?
Because a cup measures volume, but ingredients have different densities. A US cup of all-purpose flour is about 120 g, while a cup of granulated sugar is 198 g, which is why the grams-to-cups tool asks which ingredient you mean.
Do these handle US, metric and imperial units?
Yes, and they keep them separate, because a US cup (236.6 mL), metric cup (250 mL) and imperial units all differ. The measurement converter flags the common pitfalls, like the US vs imperial gallon and the 20 mL Australian tablespoon.
