The Useful Units Recipe Converter scans digital or printed recipes, automatically recognizes the text and converts the amounts of the ingredients into your preferred units, including volume to weight conversions.

"Finally: The app I always wanted and never found." Susanne Tobler, Founder & Owner of TASTELAB

Confused by cups, ounces, pints and pinches?
Don't own a scale and want to do everything by volume?
Here comes the solution to all your cooking unit conversion issues!

Simply take a picture from a cookbook or a screenshot from a digital source - and the app does all the work for you: it automatically reads the recipe and instantly converts it into your preferred units.

Unlike many other recipe unit converters, Useful Units is smart and also knows about the specific weight of many ingredients. This way, you can convert between volumes and weights seamlessly!



A recipe in cookbook or on your favourite blog? Useful Units isn’t picky: Take a picture of the recipe or just load a screenshot of it. Text recognition is automatic! Adjusting or adding ingredients manually is super easy, too.


We all have our favourite units.
Grams, milliliters or liters? Sure.
Cups, pints and pounds? Yes.
Pinches, dashes and drops? Yep, that as well.
Choose the units you like best - and switch between them super easily!


Useful Units is for free and always will be. Of course: You can tip us - as much or as little as you like.


Currently, the Useful Units Recipe Converter recognizes the following units with most of their common abbreviations:

* Units of Volume: Liters (as well as deciliters, centiliters and milliliters), tablespoons, teaspoons; drops, pinches and dashes as well as sticks (for all things buttery). Furthermore US and Imperial fluid ounces, gills, cups, pints, quarts and gallons.
* Units of Weight: Kilograms (as well as grams and milligrams), pounds, slugs and ounces.

If you think that’s not enough: Let us know!
If you think that’s too many: Never mind! Just don’t select them in the menu and they won't be displayed!


Is a cup of salt heavier than a cup of flour? Certainly so!

The Useful Units Recipe Converter knows the density (yay, science!) of more than 300 of the most common baking and cooking ingredients, so you don’t have to worry about these things when converting.

What about all the other ingredients? No problem: Just tell the app what category it belongs to and the app will do the rest for you.


Double or quadruple the recipe’s amounts? Sure, just a click.
Throwing a giant party with food for everyone? Great! Just enter your custom scaling factor and that’s it!


The Useful Units app is written completely in English.
Yet, it does recognize English and German recipes, units and ingredients.

We hope this neat little app brings you as much joy while cooking and baking as it does to us!

We are very interested in your feedback. If you have any inputs, questions or concerns, please contact us at

Cook and bake away! Sue & Remo

Useful Unit Recipe Converter

Took the picture, and nothing happened. Wanted to convert grams into US. What is wrong, I read all instructions twice....

Developer Response ,

Dear app user,
Sorry that we caused you such hassle!
We're aware that some versions of the app didn't run smoothly (or at all) on some devices.
We've since updated the app and it should now run on more devices.
Do give it another try!
Best regards, the Tastelab team

Looked like a good idea. Scanned a British recipe, it picked up all of the items and amounts correctly; DID NOT DO ANY CONVERSION to U.S. metrics. It just repeated the quantities as listed. Skip this one.
