The recipe unit converter
that gets baking right.

Paste, photograph, or link any recipe and get every measurement converted — cups to grams, tablespoons to ml, °F to °C and Gas Mark, all at once. Unlike generic converters, RecipeScan uses real ingredient density data, so bread flour, brown sugar, and cocoa powder all convert correctly.

RecipeScan is a free recipe unit converter built specifically for bakers and home cooks who work across different measurement systems. Whether you're converting an American recipe to UK measurements, scaling a cake recipe for a larger tin, or just trying to figure out how many grams are in a cup of plain flour — RecipeScan gives you the accurate answer, not a one-size-fits-all approximation. The AI scanner goes further: point it at any recipe — a URL, a photo, a scanned cookbook page — and it converts the entire thing in one go.

How it works

Three ways to convert any recipe

Paste text, upload a photo or PDF, or drop in a URL — RecipeScan handles all three and converts every measurement automatically.

01
Paste or type it in

Copy a recipe from anywhere — a website, a message, a screenshot — and paste it straight into the converter. RecipeScan reads it and pulls out every measurement.

02
Upload a photo or PDF

Got a recipe card, a magazine clipping, or a PDF cookbook? Upload the image or file and the AI scanner extracts all the ingredients automatically.

03
Drop in a URL

Found a recipe on a blog or food site? Paste the link and RecipeScan fetches and converts the ingredients — no more switching tabs to do the maths.

Features

More accurate than any other converter

Generic converters use a fixed "1 cup = 240ml" rule for everything. RecipeScan uses actual ingredient density data — because a cup of bread flour and a cup of icing sugar are not the same weight.

Density-accurate conversions

150+ ingredients with real density data — plain flour, bread flour, self-raising, brown sugar, icing sugar, cocoa powder, nuts, chocolate, and more. A cup of packed brown sugar weighs 220g. A cup of sifted icing sugar weighs 120g. RecipeScan knows the difference. ChatGPT and Google don't.

Oven temperature converter

°F, °C, and Gas Mark — all three, live. Includes an oven dial visual and plain-English descriptions like "moderate oven" so you never have to guess.

Servings scaler

Scale any recipe up or down with a tap. Baking-aware warnings flag when leavening agents (baking powder, yeast) don't scale linearly — a mistake that ruins cakes.

AI recipe scanner

Scan photos, PDFs, and URLs with AI that understands recipe structure — not just raw text extraction. It handles fractions, ranges ("1–2 tbsp"), and ingredient-name variations between American and British recipes. Paste a URL from any food blog and get back a fully converted ingredient list in seconds.

FAQ

Good questions.

What is RecipeScan?
RecipeScan is a recipe unit converter and AI scanner. You can convert cups to grams, tablespoons to ml, scale servings, convert oven temperatures, and use AI to scan any recipe from text, a photo, a PDF, or a URL.
Is it free to use?
Yes — sign up and get 5 free scans with no card required. The unit converter and temperature tools are always free. Scans (AI recipe processing) use credits, which you top up when needed.
How accurate are the conversions?
Very. Unlike generic converters, RecipeScan uses real ingredient density data for 150+ ingredients. That means different values for bread flour vs plain flour, packed brown sugar vs loose, and so on.
What units does it convert between?
Grams, cups, tablespoons, teaspoons, fluid ounces, and millilitres. The temperature converter handles °F, °C, and Gas Mark simultaneously.
What counts as a scan?
Any AI recipe processing — whether you paste text, upload an image or PDF, or enter a URL. Each submission uses one scan credit. The manual unit converter never uses credits.
Do scan credits expire?
No. Credits are yours to keep and use whenever you like — no monthly resets, no expiry dates. Top up once and use them over as many months as you want.
Is there a subscription?
No. RecipeScan is entirely pay-as-you-go. You only pay when you want more scan credits. There are no monthly charges, no annual plans, and no auto-renewals.
What payment methods are accepted?
All major credit and debit cards, plus Apple Pay and Google Pay, processed securely by Paddle. Prices include applicable taxes.
How do I convert an American recipe to UK measurements?
American recipes use volume measurements (cups, tablespoons, teaspoons) while UK recipes typically use weight in grams. The conversion isn't fixed — it depends on the ingredient. A cup of flour is around 120–130g, but a cup of butter is 227g and a cup of sugar is 200g. RecipeScan handles all of these automatically, including converting Fahrenheit oven temperatures to Celsius and Gas Mark.
What is the difference between cups and grams in baking?
Cups measure volume; grams measure weight. For liquids they're roughly equivalent, but for dry ingredients the difference is significant — and varies by ingredient. A cup of sifted flour weighs much less than a cup of packed flour. Professional bakers use grams because weight is precise regardless of how you fill the cup. RecipeScan converts both ways, using ingredient-specific density data for accuracy.
