Enter the total amount of flower (ounces) and the total pounds of butter (lbs) into the Cannabutter Ratio Calculator. The calculator will evaluate and display the Cannabutter Ratio. 

Cannabutter Ratio Formula

The following formula is used to calculate the Cannabutter Ratio. 

CBR = F / B 

  • Where CBR is the Cannabutter Ratio (Flower: 1 Butter)
  • F is the total amount of flower (ounces) 
  • B is the total pounds of butter (lbs) 

How to Calculate Cannabutter Ratio?

The following example problems outline how to calculate Cannabutter Ratio.

Example Problem #1:

  1. First, determine the total amount of flower (ounces). 
    • The total amount of flower (ounces) is given as: 3.
  2. Next, determine the total pounds of butter (lbs). 
    • The total pounds of butter (lbs) is provided as: 4.
  3. Finally, calculate the Cannabutter Ratio using the equation above: 

CBR = F / B 

The values given above are inserted into the equation below and the solution is calculated:

CBR = 3 / 4  = .75:1 (Flower: 1 Butter)


Example Problem #2: 

For this problem, the variables required are provided below:

total amount of flower (ounces) = 6

total pounds of butter (lbs) = 4

Test your knowledge using the equation and check your answer with the calculator above.

CBR = F / B  = ?
