Scale any recipe to any serving size. Free, no signup, works offline.
Volume-to-weight conversions use approximate densities (grams per cup). Edit them below.
Recipe math is where weeknight dinners go wrong, so this tool does it two ways. On the Scale tab, enter what the recipe makes and what you want instead, or tap the half, double, or triple presets. Paste your ingredient list into the box, one ingredient per line, and the scaled list updates as you type.
The parser understands fractions, mixed numbers, ranges, and even unicode fractions, so "1 1/2 cups" and "2-3 cloves" scale correctly, while lines like "Salt to taste" pass through unchanged. Amounts get smart unit switching: small amounts stay in teaspoons or ounces while larger ones convert up to tablespoons, cups, quarts, or pounds automatically. Use the Copy button to take the finished list to the store or the kitchen.
On the Convert tab, enter an amount and pick any two units across US volume, metric volume, US weight, and metric weight. If the conversion crosses from volume to weight, pick the ingredient and the tool uses its density from the editable grams-per-cup table, which you can adjust and reset to defaults any time.
Example only, not typical earnings/pricing/numbers. A recipe makes 4 servings and you want 6, so the scaling factor is x1.5. "2 cups flour" becomes "3 cups", "1/2 tsp salt" becomes "3/4 tsp", "1.5 lb chicken" becomes "2 1/4 lb", and "2-3 cloves garlic" becomes "3 - 4 1/2 cloves", while "Salt to taste" passes through untouched. On the Convert tab, entering 1 cup to grams with All-purpose flour selected gives "120 g" with a note that it is approximate, based on about 120 grams per cup. Change the density in the table and the conversion updates immediately.
It parses standard fractions, mixed numbers like "1 1/2", unicode fractions, and ranges like "2-3", scaling each endpoint of a range separately. Amounts round to kitchen-friendly fractions.
Smart unit switching keeps quantities readable. Small amounts stay in teaspoons and ounces; when scaling up, the tool converts to larger units like tablespoons, cups, or pounds so you are not reading "48 teaspoons."
They pass through unchanged and are shown dimmed in the scaled list, since there is nothing to scale.
They are approximate, based on grams-per-cup densities you can see and edit in the density table. A cup of honey weighs far more than a cup of flour, so check the table value for your ingredient before baking something precise.
Yes. The header notes it works offline, and your recipes never leave your device.
