The recipe converter (also known as a recipe calculator, recipe multiplier, recipe divider, or serving sizer) is a kitchen tool that can be used to help you multiply, divide, portion, or scale your recipes to a desired yield or serving size. It's almost as easy as copy, paste, convert.

View the video tutorial, see the instructions below, or visit the How-To section for details on how to use the recipe converter.

How to use the Recipe Converter

(Recipe Calculator / Recipe Multiplier / Recipe Divider / Serving Sizer)

1. Enter the title of the recipe (optional)
2. Type in or copy and paste the ingredients section of a recipe into the ingredients text area.

*Note: The copy and paste feature may not work properly for some recipe sites or food blogs due to the way the site formats their text. If this happens, the ingredients can be typed in or each line that was pasted into the text area can be edited. See below comments for details.

3. If necessary, edit the ingredients so that they are in standard recipe format and each word or number is separated by a space.
(The standard recipe format for ingredients starts with the quantity, followed by the unit measure, and ends with the ingredient.)
example: 1 quart milk

4. Edit the recipe so that each ingredient line is on a new line. (New lines are created by pressing enter.)
1 cup milk
2 Tbs sugar
1 tsp salt

5. Edit each line so that quantities and words are separated by a space.
6. Check the "Round conversion to nearest cooking fraction" box if you want the converted ingredient quantities to be rounded to the nearest cooking fraction. (Checked by default)
7. Check the "Include original recipe in conversion" box if you want to include the original recipe in the converted recipe text area. (Unchecked by default)
8. Click the corresponding tab to choose to convert by portion or by multiplier/divider.
9. Input a recipe multiplier/divider, or enter an original (serving/yield) and a desired size(serving/yield).
10. Press the multiply, divide, or portion button and the converted recipe will be displayed in the converted recipe text area.

*Note: Only numbers placed at the beginning of each line will be converted. See below comments for details.

11. Check the converted recipe for correctness. If necessary, the converted recipe can be manually edited.
12. The converted recipe can be printed or copied and pasted into a document.

(a) Fractions can be entered as a quantity. When using fractions, separate whole numbers from fractions with a space.
One-third = "1/3", one and one-half = "1 1/2".

(b) Make sure to remove any bullet points that may appear before the quantity or at the start of each line.

(c) Ingredients do not require a unit measure.
1 watermelon = "1 watermelon".

(d) Ingredients that have a quantity range will not convert properly.
"3 to 4 cups bananas" (multiplied by 2) will be converted to: "6 to 4 cups bananas"
"3-4 cups bananas" (multiplied by 2) will display an NaN (Not a number) error: "NaN cups bananas"

(e) Always check the converted recipe for correctness.
(f) Check to make sure the cooking/baking instructions are updated as a result of the conversion.
