Enter the amount of Ingredient A and the ratio of Ingredient A to B into the calculator to determine the required amount of Ingredient B. This calculator helps in maintaining the correct proportions for recipes.

Cooking Ratio Formula

The following formula is used to calculate the amount of Ingredient B based on the amount of Ingredient A and the ratio of A to B.

B = A / (A:B)

Variables:

  • A is the amount of Ingredient A (grams)
  • (A:B) is the ratio of Ingredient A to Ingredient B
  • B is the amount of Ingredient B (grams)

To calculate the amount of Ingredient B, divide the amount of Ingredient A by the ratio of A to B.

What is a Cooking Ratio?

A cooking ratio is a proportional relationship between ingredients used in recipes. It ensures that the balance of flavors and textures is maintained, regardless of the quantity being prepared. Ratios are fundamental in cooking and baking, allowing for scalability and consistency in dishes.

How to Calculate Ingredient B?

The following steps outline how to calculate the amount of Ingredient B needed when given the amount of Ingredient A and the ratio of A to B.


  1. First, determine the amount of Ingredient A used in the recipe (A) in grams.
  2. Next, determine the ratio of Ingredient A to Ingredient B (A:B).
  3. Use the formula B = A / (A:B) to calculate the amount of Ingredient B.
  4. Finally, measure out the calculated amount of Ingredient B in grams.
  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.
