Enter the total ingredient weight used and the total ingredient weight required by the recipe into the Baking Ratio Calculator (use a mass basis such as g, kg, oz, or lb). The calculator will evaluate and display the baking ratio, which functions as a dimensionless scale factor (used ÷ required).

Baking Ratio (Scale Factor) Formula
The following formula is used to calculate the Baking Ratio (scale factor).
BKR = IU / IR
- Where BKR is the Baking Ratio (unitless scale factor)
- IU is the total ingredient weight used (sum of ingredient weights on a mass basis)
- IR is the total ingredient weight required by the recipe (sum of ingredient weights on a mass basis)
To calculate the baking ratio, divide the total ingredient weight used by the total ingredient weight required by the recipe. In practice, recipe scaling is often done by choosing a single reference (such as flour weight or yield) and applying the same scale factor to each ingredient.
How to Calculate Baking Ratio?
The following example problems outline how to calculate Baking Ratio.
Example Problem #1:
- First, determine the total ingredient weight used.
- The total ingredient weight used is given as: 30 (in any mass unit).
- Next, determine the total ingredient weight required by the recipe.
- The total ingredient weight required by the recipe is provided as: 20 (in the same mass unit).
- Finally, calculate the Baking Ratio using the equation above:
BKR = IU / IR
The values given above are inserted into the equation below and the solution is calculated:
BKR = 30 / 20 = 1.5
Example Problem #2:
For this problem, the variables required are provided below:
total ingredient weight used = 60
total ingredient weight required by recipe = 40
Test your knowledge using the equation and check your answer with the calculator above.
BKR = IU / IR = ?
