How many of us struggle with "kitchen math?" The Kitchen Calculator PRO app makes cooking and measuring so much easier. Kitchen Calculator PRO does all the recipe conversions for you, and makes it simple to scale recipes up (or down) to change the number of servings the recipe yields. With Kitchen Calculator PRO you can:

1.Quickly scale your recipes (add, subtract, multiply, divide) using fractions!

2.Convert ingredients from weight to volume, and vice versa ( cups to grams, ounces, etc. )

3.Supports several volume, weight, distance, and temperature conversions

4.Enter amounts and view results in standard cooking fractions (1/2, 1/3, etc )

5.Grow a database with your favorite ingredients! (see weight to volume )

***** Brilliant - "For a cook trained in the metric system, this tool is a dream come true" by BeeDiana.


Easily convert and scale recipes in an instant. Doubling a recipe (or cutting a recipe in half) is simpler than ever before, with all the most common units of cooking measurement right at your fingertips.


What is so special about weight to volume conversions?

When converting from weight to volume it is important to take into account the ingredient you are converting. As you know, a cup of sugar does not weigh the same as a cup of rice. Furthermore, a particular brand of sugar may weigh different from another. This is all made easy with Kitchen Calculator PRO.

So, how does Kitchen Calculator handle weight to volume conversions?

1.It comes with a database of common ingredients based on weight figures from the USDA (US Department of Agriculture).

2.It allows you to quickly enter and save your own ingredient weight for more precise conversions. In many cases, you can enter the values right off the product label, using fractions!

3.Kitchen Calculator will remember any saved ingredient information for future conversions.

NOTE: The preset ingredient list is based on USDA (US Department of Agriculture) figures and are approximate values. They may differ from the ingredients you use. For precise calculations we recommend entering the weights for your ingredients and, whenever possible using a scale.

Near perfect!

I really like the interface and functionality of this app. Will be extremely useful in my work as a catering chef. A couple of suggestions for future versions that would make this the ultimate solution. A built in timer so i don't have to leave the app for that, and a recipe scaling feature for easier conversions i.e - I input the parameters such as "serves 2 into serves 6" and as I enter amounts they are scaled automatically.
A marvellous tool, thanks much!

Power and Efficiency in the Kitchen!

Have you ever found yourself in this situation: you have a great recipe, but it calls for the wrong number of people and you're going crazy trying to figure out the right amounts of ingredients to fit a particular number of servings. Or the recipe calls for units you're not particularly familiar with and you would like to use those units of measurements that work for you? Well now you can, with Kitchen Calculator Pro! It quickly scales recipes to the amounts you want, also using standard cooking fractions, and converts all kinds of units, including weight to volume! Did I mention that there's already a list of ingredients to select from and convert to the desired unit, and if the ingredient is not there you can add it? I've had experience with various converting apps, but this is by FAR the most POWERFUL and EFFICIENT app I've come across! The developer's name is Forward Leap. The name fits the app!!!

Feature request - Change ingredient without starting over

I've tried emailing the developer but it bounces back. So maybe they'll see my request, here.

This is a great app but I wish they would make one improvement:

I often convert several ingredients using the same measurement. E.g. cups to grams. It's easy enough to switch between units but the only way to change the ingredient is to start completely over. This is tedious and time consuming. I'd love for the next version to allow for quickly changing the ingredient without having to also reselect the units.
