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 recipe converter will scale a recipe's ingredients from one number of servings to another, or from one baking pan size and shape to another. Whether you need to increase, reduce, double, halve, etc., the recipe scaler on this page will adjust the ingredients in the blink of an eye.

You can either enter the recipe ingredients line by line, or you can paste-in a recipe's ingredient list all at once and have the calculator load it into the form for you. Super cool!

Also, the calculator gives you the following options for entering/calculating the conversion factor (multiplier):

  • Enter the starting and ending number of servings.
  • Select from a preset scaling menu (quarter, half, double, etc.).
  • Set the original and new baking or cake pan sizes.
  • Manually enter the conversion factor.

Plus, you can choose to include the metric equivalents for each converted ingredient measurement. And for dry measurements, the calculator will even try to match each ingredient with its own unique weight factor (flour, sugar, chocolate chips, etc.).

And finally, 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 converted unit quantities.

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!

VIDEO: How To Use The Recipe Conversion Calculator

I suggest you pause the video after watching each section. Then use that section of the calculator. Then continue watching the video for a demonstration of how to use the next section.




With that, let's use the Recipe Conversion Calculator to scale a recipe's ingredients up or down.

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

Next, if you are able to copy a properly formatted recipe, paste the recipe into the large field and click the "Load Recipe Into Form" button.

If you are unable to paste in a properly formatted recipe, then 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 video above the calculator, and 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 calculator does not save your work, so be sure to print out a hard copy of the results before leaving this page (or subscribe to the ad-free, member version which allows you to save your work).

Updated January 20, 2017: Added the option to paste-in an ingredient list. Added grams and kilograms to the unit of measurement select menus. Added an option to include metric equivalents in the report. 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.

Recipe title: Enter the title of the recipe, which will appear on the printed recipe conversion.

Set Recipe Conversion Factor section: Click the radio button of the method you would like to use to calculate the conversion factor, and then complete the entries/selections for the chosen method. Once the required entries/selections are made for the chosen method, the final conversion factor will be calculated and displayed.

Option #1 - Adjust number of servings: Enter the original number of servings and the number of desired servings. The converter will automatically calculate the conversion factor and enter it into the appropriate field.

Option #2 - Select scale to set conversion factor: Select the desired recipe adjustment from the drop-down menu. The converter will automatically calculate the conversion factor and enter it into the appropriate field.

Option #3 - From one cake pan/size to another: Optional: Select the pan shape and number of layers and enter the height and dimensions (diameter for round, or width and length for rectangle). The converter will automatically calculate the conversion factor and enter it into the appropriate field. Please enter all dimensions as decimals (example: 2-1/2 would be entered as 2.5).

Option #4 - Manually enter conversion factor: If you did not complete Options #1, #2, or #3, manually enter the conversion factor here. Please enter as a whole number or decimal (example: 2-1/2 would be entered as 2.5).

Final conversion factor: If you completed any of the 4 conversion options this field will contain the final conversion factor (multiplier), which is required before the calculator will convert the ingredients.

Enter Recipe Ingredients

Optional: Paste In Recipe Ingredients: If you are able to copy the recipe ingredients and paste them into the large field in this section, the calculator will attempt to load the ingredients and measurements into the conversion form for you (hopefully saving you time). The calculator expects the pasted ingredients to be whole-number fraction unit description, with a space in between each, and a new line for each ingredient. Also, the first character on each line must be numeric, so precede decimal points with a zero (enter .5 as 0.5).

2 1/4 cups all-purpose flour
1 teaspoon salt
3/4 cup sugar
2 large eggs.

Be sure to check/edit the formatting before clicking the Load Ingredients Into Form button. When ready, click the button and then edit the loaded ingredients as needed.

Quantity column: Enter a quantity for each ingredient. Whole numbers are to be entered in the left-hand fields (no non-numeric characters), while fractional quantities can be selected in the right-hand drop-down menus. Note that the quantity (whole number plus fraction) must be greater than zero for the calculator to include the line in the recipe conversions.

Unit of Measurement column: Select the unit of measurement that corresponds to each quantity entered.

Ingredient Description column: Enter the ingredient descriptions as you want them to appear on the printed recipe conversion.

Include metric equivalents: If you would like the estimated metric equivalents of the conversion to be included in the report, place a checkmark in this checkbox.

Recipe Instructions (Optional): Enter any recipe instructions you want to appear on the printed recipe conversion.
