THE RECIPE WORKBENCH

Recipe conversion calculator.
Scale, check, then cook.

Use it as a recipe converter, recipe scaler or recipe multiplier: enter the original and new servings, paste the ingredients and get every scaled amount to review.
Quantities in the method are checked too. Prefer half the recipe? Try the half recipe calculator.

Made for the details

Fractions & ranges
“Plus” quantities
Package sizes kept intact

01 / YOUR RECIPE

Start with what you have.

Positive numbers or fractions, such as 4, 6 or 1½.

English ingredient notation. Paste your own recipe; no URL import.

Your recipe stays in this browser tab. No sign-in.

02 / YOUR REVIEW

Every amount, in view.

A little care before you cook.

Your original and scaled amounts will appear here. Edit anything that needs a human decision, then confirm each line.

These never get multiplied automatically.

A CLEARER WAY TO SCALE

01

Scale the full quantity.

Mixed and Unicode fractions, range endpoints, and quantities after “plus” are handled together. Units are kept as written.

02

Keep the context.

Two 14-ounce cans become three cans when you scale by 1.5. The 14-ounce package size stays the same. Other parenthetical numbers are flagged.

03

Leave with a checked copy.

Unknown notation is left unchanged with a note. Adjust the results yourself and export a record of the original, your edits, and the review notes.

QUESTIONS ABOUT SCALING

How do I convert a recipe to a different number of servings?

Enter the original servings and the new servings. The tool divides one by the other to get a scale factor and applies it to each ingredient quantity. Four servings to six, for example, is a factor of 1.5.

How do I double or multiply a recipe?

Set the new servings to twice (or any multiple of) the original. For a doubled recipe, 4 servings becomes 8. Check the cooking time, temperature and pan size yourself; they are not multiplied.

Does this convert units like cups to grams?

No. Units are kept as written and only quantities change. If you need cups converted to grams or ounces, convert the recipe separately and then scale it here.

A calculator, with room for judgment.

No unit conversion, nutrition estimates or cooking guarantees. Scaling changes quantities; it does not determine cooking times, safe temperatures, pan capacity, or whether a recipe will work at a new size.

Privacy & measurement

Ingredients, steps and edited results are processed in this tab, without being sent to a server or saved by this app. Closing or reloading the tab clears recipe content. Copy and download are your choice.

We measure anonymous page visits, review starts, explicit result confirmations and exports. A random session identifier is kept in sessionStorage, and only the last visit date is kept in localStorage to recognize a return within 60 days. Neither stores recipe content. Test visits use ?test=1 and are separated from ordinary use.
