We have designed this automatic weight calculator to compute the weight of your fish based on the length and girth.  All you have to do is fill in the length and girth fields, then "Click" the "Compute" button to view the weight of your fish.

We recommend you "Clear the Fields" if you wish to do multiple fish calculations.

Enter partial length and girth measurements as decimals: 1/4"=.25; 1/2"=.50; 3/4"=.75

Girth is optional, default is calculated at 0.46 * Length

Please Note: Actual Girth measuements will make for closer weight calculations
