Recipe Conversion Calculator for
Cooking Measurement Conversions

[ Skip to Calculator ] Calcy pointing down

The Recipe Conversion Calculator on this page will scale cooking measurements to accommodate a greater or lesser number of servings.

This free online cooking measurement conversions calculator will scale a recipe's ingredients using any one of four recipe conversion options.

You can enter an alternate number of servings, or you can select from a preset scaling menu (quarter, half, double, etc.), or you can set the original and new pan/cake sizes, or you can manually enter the conversion factor.

Plus, unlike other online recipe converters, this converter will provide you with a printer friendly version so you can print out the completed conversion -- which will include a column containing the original unit quantities and a column containing the the converted unit quantities.

Common Recipe Conversions

The following recipe conversions chart shows some of the common recipe conversions in case you would like to convert an ingredient manually.

Common Recipe Conversions

Unit(s) = Unit(s)
Pinch = 1/16 Teaspoon (tsp)
3 Teaspoons = 1 Tablespoon (tbsp)
1 Tablespoon = 1/2 Fluid Ounce (fl oz)
8 Fluid Ounces = 1 Cup
2 Cups = 1 Pint (pt)
2 Pints = 1 Quart (qt)
4 Quarts = 1 Gallon (gal)
16 Dry Ounces = 1 Pound (lb)

Note that all measurements are in U.S. and may have alternate interpretations.

Calculator Referenced by Chef/Author Kristi Ambrose!

On September 3, 2013, I received the following email from the author of a new cookbook series:

I have seen a lot, and I mean A LOT of cooking conversion sites out there, but this one is by far the best. I am using it in a lot of cookbooks I am writing and will give you full credit on your help! Thanks again for making my life easier." -- Kristi Ambrose

Well, little did I know the first book in her series would be available on Amazon the following month. And sure enough, there it was ... an entire paragraph devoted to referencing the calculator. How cool is that?!

Of course, I felt compelled to return the favor, so, here you go Kristi ...

For Love of Eggs Cover Image

Kristi Ambrose is in the process of creating a very yummy cookbook series, For The Love Of. According to the author, the cookbooks are best viewed in color and you don't even need a Kindle to read them!

Take a free "Look Inside" For the Love of Eggs on Amazon (reference to the calculator is on the first page of text, 3rd paragraph).

With that, let's use the Recipe Conversion Calculator to calculate cooking measurement conversions when scaling a recipe from one number of servings to another.

Instructions: Enter the title of the recipe and then use one of the four multiplier options to set the conversion factor.

Next, for each ingredient, enter the whole number and/or select a fraction indicating the original quantity, select the corresponding unit of measurement, enter a description of the ingredient, and then click the "Convert Recipe" button.

Mouse over the blue question marks for a further explanation of each entry field. More in-depth explanations can be found in the glossary of terms located beneath the Recipe Conversion Calculator.

Important: Please double-check the results before combining the ingredients as this calculator comes with no guarantee of accuracy (I can't test all possible entry variations). Also, the recipe conversion calculator does not save your work, so be sure to print out a hard copy of the results before leaving this page.

Updated May 31, 2016: Radio buttons were added to Set Recipe Conversion Factor section. If you used the calculator prior to the upgrade date, please refresh/reload the page a couple of times to insure you are using the latest version instead of the older version which may be cached (stored) in your web browser software's memory.
