Enter the fish weight (grams) and the fish length (cm) into the Calculator. The calculator will evaluate the Condition Factor. 

Condition Factor Formula

K = 100 * W/L^3


  • K is the Condition Factor (100g/cm^3)
  • W is the fish weight (grams)
  • L is the fish length (cm)

To calculate the Condition Factor, divide the fish weight by the fish length cubed, then multiply the result by 100.

How to Calculate Condition Factor?

The following steps outline how to calculate the Condition Factor.

  1. First, determine the fish weight (grams). 
  2. Next, determine the fish length (cm). 
  3. Next, gather the formula from above = K = 100 * W/L^3.
  4. Finally, calculate the Condition Factor.
  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.

fish weight (grams) = 30

fish length (cm) = 15
