Koi Weight Based on Length Calculator
When using this calcuator make sure you have taken note what type of Koi you have, as different breeds have a slightly different body shape and this should be considered in relation to the weight given by this formula.
How to Use:
Enter the length of the fish in inches or cm.
For a normal Koi, the length would be from the mouth to the end of the tail.
For a long fin Koi, Use the length from the mouth to the start of the tail and be sure to check the LF box.
