Enter the bitterness units and the gravity units into the Calculator. The calculator will evaluate the Bitterness Ratio. 

Bitterness Ratio Formula

BR = BU / GU


  • BR is the Bitterness Ratio ()
  • BU is the bitterness units
  • GU is the gravity units

To calculate Bitterness Ratio, divide the bitterness units by the gravity units.

How to Calculate Bitterness Ratio?

The following steps outline how to calculate the Bitterness Ratio.

  1. First, determine the bitterness units. 
  2. Next, determine the gravity units. 
  3. Next, gather the formula from above = BR = BU / GU.
  4. Finally, calculate the Bitterness Ratio.
  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.

bitterness units = 1.05

gravity units = 30
