Free kitchen tools for home cooks: scale recipes up or down, convert cups to grams, find ingredient substitutions, and calculate calories per serving — all in one cheerful kitchen toolkit. Paste, snap a photo, or type your recipe in.
Choose how much to multiply by — halve it, double it, or pick your own factor. Quantities are converted with friendly fractions where it makes sense.
One ingredient per line. Fractions like 1/2, mixed numbers like 1 1/2, and decimals all work.
Grams to ounces, cups to milliliters, pints to quarts — and a quick reference card showing every common conversion at once.
Volume-to-weight conversions for cooking ingredients (like flour or sugar) vary by what's in the cup. For ingredient-specific weights, check the calorie counter, which uses standard food densities.
Out of an ingredient? Type what you need and see practical substitutes with ratios and notes on how they'll change the dish.
Get a calorie estimate for the whole recipe and broken down per portion. Uses a built-in food database — works best when ingredient names are clear.
Tip: include amounts and units — "1 cup flour" works better than just "flour."
Why cup measurements lie, how grams save your baking, and the exact weight of every common ingredient by the cup.
