Paste a recipe, set your servings, and get accurate scaled quantities with gram conversions. Runs entirely in your browser — no account, no servers, completely private.
From paste to scaled recipe in under a minute. No sign-up, no fuss.
Type your recipe name and set the original and desired serving counts. Use the quick-multiplier buttons (½×, 2×, 3×…) for instant scaling.
Paste a full recipe and click “Auto-parse” to extract ingredients automatically, or add them one by one. Select known ingredients for density-accurate gram conversions.
Paste your cooking steps — times like “30 minutes” scale proportionally. Add personal notes or substitutions for reference.
Click Scale & Convert to see results. Copy to clipboard, save to your browser, print, or export as PDF via your browser’s print dialog.
Switch to the Unit Converter tab to convert volumes, weights, and temperatures — or browse the Density Chart for per-ingredient gram references.

Not all recipes scale equally. Here’s what experienced cooks know.
A cup of flour can weigh anywhere from 100g to 170g depending on how it’s packed. For baking, always use a kitchen scale. Our tool shows gram equivalents alongside volume. Read why →
Baking powder and baking soda don’t scale linearly. When multiplying by more than 2×, use only 75–80% of the calculated amount to avoid metallic bitterness. Learn more →
Doubling a recipe doesn’t mean double the oven time. A doubled batch typically takes 10–20% longer — trust a thermometer over the clock, not just the scaled time estimate.
Honey is far heavier than water per cup. Select the correct ingredient name in the tool for density-accurate gram results. Use the Density Chart tab for a full reference table.
A 9×13 pan has about twice the area of an 8×8. Use area ratios when switching pans. Dense batters in under-sized pans can overflow — split across multiple vessels when in doubt.
Oven temperature generally doesn’t change when scaling. The exception: dramatically thicker items sometimes benefit from a slightly lower temperature to cook through without overbrowning.

Everything you need to know about scaling recipes with our tool.
Recipe Scaler exists to make precise cooking accessible to everyone. Whether you’re halving a batch of cookies or tripling a lasagne for a crowd, accurate scaling makes the difference between a dish that works and one that doesn’t.
Our tool runs entirely in your browser — no servers, no accounts, no tracking. Recipes saved using the tool are stored only in your device’s localStorage and never leave your machine.
We use density-based weight equivalents to ensure conversions are as accurate as possible — because a cup of flour can vary by 50g depending on how it’s measured.
