Cooking & Food

Scale a recipe up or down: paste the ingredient list, set the new servings, and every quantity — including fractions like 1 1/2 — is recalculated.

Convert grams to cups, tablespoons and teaspoons — and back — for flour, sugar, butter, milk, oats and 20 common baking ingredients.

Convert oven temperatures between °F, °C, fan (convection) and gas mark — and convert oven recipes to air fryer temperature and time.

Convert butter between US sticks, cups, tablespoons, grams and ounces — handy for international recipes.

Adapt a recipe to a different pan size — round, square or rectangular — with the scaling factor for ingredients and tips for baking time.

Safe minimum internal temperatures for beef, pork, poultry, fish and leftovers (USDA), plus a turkey roasting time calculator by weight.

Find how much water to use for white, basmati, jasmine, brown, wild or sushi rice — stovetop or rice cooker — for any amount of rice.

Get the right coffee-to-water ratio for pour-over, drip, French press, AeroPress, espresso or cold brew — grams of coffee for any cup size, or water for your dose.

Build bread or pizza dough by baker's percentages: flour, water (hydration), salt and yeast in grams for any number of dough balls.

Plan a sourdough bake backwards from when you want bread: when to feed the starter, mix, bulk ferment, shape, cold-proof and bake — adjusted for kitchen temperature.

Calculate salt for a brine by percentage — for turkey, pork, pickles or fermentation — or an equilibrium brine based on food plus water weight.

Plan how much food and drink to buy for a party — appetizers, mains, sides, desserts, wine, beer, spirits, soft drinks and ice — by guests and hours.

Calculate alcohol by volume for homebrewed beer, wine or cider from original and final gravity — or the strength of a mixed cocktail from its ingredients.

Price a dish from its ingredient cost and target food-cost percentage, and see the gross profit per plate — the method restaurants use for menu pricing.

Find how many servings a round or square cake gives — party-size or wedding-size slices — or which tiers you need for a number of guests.
