Free Recipe Converter Online — Scale Any Recipe in Seconds
Cooking for two instead of eight? Doubling a cake for a celebration? Our free recipe converter does all the math for you — instantly, right in your browser. Paste any ingredient list, set your scale, and every quantity recalculates in real time. No downloads, no account, no cost. Just a clean, fast recipe converter online that works whenever you need it.
Recipe Scaling Calculator — Two Modes, One Tool
The recipe scaling calculator offers two ways to scale. In multiplier mode, drag a slider from 0.25× to 10× — or type any custom value — and all ingredient quantities update proportionally. In servings mode, enter your original serving count and your target; the recipe scaling factor is calculated automatically and applied to every line. Output is always displayed as clean kitchen fractions — ⅓ cup rather than 0.333 cup, 1¼ tsp rather than 1.25 tsp — with smart rounding that promotes awkward values to the nearest practical measure.
Recipe Converter Grams to Cups — Volume and Weight, Both Directions
One of the most searched cooking questions online is how to convert recipe measurements between weight and volume. Our recipe converter grams to cups feature tackles this with a built-in density database covering flour, sugar, butter, honey, oats, milk, and dozens of other everyday ingredients. Enter a cup measurement and get grams back. Enter grams and get cups. The tool handles tablespoons to milliliters, ounces to grams, and every common kitchen unit in between. Where a density estimate is applied, the output is clearly marked so you always know what is exact and what is approximate. For per-ingredient reference tables, see the ingredient conversion charts — exact gram weights for flour, butter, honey, and 56 more ingredients.
Metric Recipe Converter — Switch Between US and Metric With One Click
Following a British recipe in a US kitchen — or a US recipe with a digital scale — used to mean looking up conversion tables one ingredient at a time. The metric recipe converter mode eliminates that entirely. Select Metric and every ingredient converts to grams, kilograms, milliliters, or liters. Select Imperial and teaspoons, tablespoons, cups, fluid ounces, and pounds come back. Unit conversion applies simultaneously with your scale factor, so scaling 2× and converting to metric is a single operation, not two.
Recipe Conversion Calculator Free — With Baking Hints Included
Most recipe conversion calculator free tools stop at the math. This one goes further. When the scaling factor you choose is known to cause problems in baking — yeast quantities that don't scale linearly, leavening that can over-activate, bake times that need adjustment — the tool surfaces a contextual hint so you can adapt before you start, not after something goes wrong. Bread bakers, pastry cooks, and anyone scaling beyond 2× will find these alerts particularly useful.
Recipe Converter App — Works on Any Device, No Install Required
Unlike a native recipe converter app, this tool runs fully in the browser with no installation. It is responsive across desktop, tablet, and mobile, supports dark mode, and stores your conversion history locally so you can revisit any previous session. Share a scaled recipe via URL, copy it to your clipboard as plain text, or print it from the browser. Everything stays on your device — nothing is sent to a server.
Scaled ingredients are also sorted automatically into a categorized shopping list — Produce, Dairy & Eggs, Meat & Seafood, Pantry & Dry Goods, Spices & Herbs — with checkboxes you can tick off as you shop. The list stays in sync with your current scale factor, so adjusting the recipe updates your shopping list immediately.
Chrome Extension — Scale Recipes on Any Website
The free Recipe Converter Pro Chrome extension brings the converter directly to any recipe website. Click the toolbar icon on Allrecipes, NYT Cooking, BBC Good Food, or any site using Recipe schema markup — the ingredient list is detected automatically and opened pre-loaded in the converter. No copy-pasting, no tab-switching. Get the extension →

Frequently asked questions
- How do I half a 3/4 cup recipe?
- Half of 3/4 cup is 3/8 cup, which equals 6 tablespoons. Set the scale slider to 0.5× and Recipe Converter Pro outputs the correct fraction automatically.
- How do I double a recipe that calls for 1/3 cup?
- Doubling 1/3 cup gives 2/3 cup. Set the scale to 2× and all quantities update instantly as clean kitchen fractions.
- Can I scale baking recipes up or down safely?
- Most baking recipes scale well between 0.5× and 3×, but leavening agents like baking powder and yeast don't always scale linearly — use roughly 75% of the calculated amount when scaling up significantly. Bake times also need adjustment. The scaling hints panel surfaces these cautions automatically.
- How do you convert a recipe from cups to grams?
- Paste your ingredients and select Metric as the unit system. A built-in density database converts cup and tablespoon measurements into grams for common ingredients — flour, sugar, butter, honey, oats, milk, and more. Density-estimated results are marked est.
- Can I turn my scaled recipe into a shopping list?
- Yes. The shopping list panel generates automatically from your scaled ingredients, grouped into Produce, Dairy & Eggs, Meat & Seafood, Pantry & Dry Goods, and Spices & Herbs with checkboxes.
- Can I convert a recipe from a 9x13 pan to an 8-inch round?
- Yes. A 9×13 pan has roughly 117 sq in of base area; an 8-inch round has about 50 sq in — a ratio of approximately 0.43×. Enter 0.43 as a custom scale factor to adjust all ingredient quantities.
- Is it better to measure ingredients by weight or volume?
- Weight is more accurate, especially in baking. A cup of flour can vary by 20–30% depending on how it's scooped; a gram is always a gram. Switch to Metric mode to get gram equivalents for each ingredient.
- Do I have to enter my recipe line-by-line?
- No — paste your entire ingredient list in one go. Each ingredient should be on its own line and quantities, units, and names are detected automatically.
- What is the volume difference between an 8-inch and 9-inch round pan?
- An 8-inch round pan has about 50 sq in of base area; a 9-inch round has about 64 sq in — roughly 25% more. To scale from an 8-inch to a 9-inch pan, use a 1.27× factor. Going the other way, use 0.79×.
- Can I import a recipe directly from a URL?
- Yes — paste any recipe website URL into the Import URL field and the converter will auto-detect the ingredient list from the page's structured data. Works with Allrecipes, NYT Cooking, BBC Good Food, and any site that uses recipe JSON-LD markup.
- Is there a browser extension for Recipe Converter Pro?
- Yes — the free Chrome extension lets you scale recipes without leaving the recipe page. It auto-detects ingredients and opens them pre-loaded in the converter. Install it from the Chrome Web Store.
