Enter the original quantity of the ingredient and the doubling factor into the calculator to determine the new quantity of the ingredient. This calculator can also evaluate any of the variables given the others are known.

Recipe Doubling Formula

The following formula is used to calculate the new quantity of each ingredient when doubling a recipe.

Q2 = Q1 * D

Variables:

  • Q2 is the new quantity of the ingredient
  • Q1 is the original quantity of the ingredient
  • D is the doubling factor (2 for doubling, 3 for tripling, etc.)

To calculate the new quantity of each ingredient, multiply the original quantity of the ingredient by the doubling factor. For example, if you are doubling the recipe, the doubling factor would be 2. If you are tripling the recipe, the doubling factor would be 3, and so on.

What is a Recipe Doubling?

Recipe doubling refers to the process of multiplying all the ingredients in a recipe by two in order to make twice the amount of the original recipe. This is often done when cooking for a larger group of people or wanting to have leftovers. It’s important to note that not all recipes can be easily doubled, as some ingredients or cooking times may not scale up perfectly.

How to Calculate Recipe Doubling?

The following steps outline how to calculate the Recipe Doubling.


  1. First, determine the original quantity of the ingredient (Q1).
  2. Next, determine the doubling factor (D).
  3. Next, use the formula Q2 = Q1 * D to calculate the new quantity of the ingredient (Q2).
  4. Finally, calculate the Recipe Doubling.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.
