FISH WEIGHT CALCULATOR
Have you ever wondered how much your "catch-n-release" trophy weighed? Well, here's where to get a pretty good idea.

If you provide the length, the calculator will give you the girth and weight. If you took the time to measure the girth as well, put that in for a more accurate weight.

Try it out. It's especially interesting if you happen to bring home a salmon. Let me know if it's accurate for you.

Notes
This calculator requires browser support for Javascript.

The fish weight estimation algorithm was originally posted to the Flyfish listserver in July of 1994, and since has been presented in a multitude of formats on various websites.

The algorithm used is W=(L * (G^2))/R, where:

W = Weight in decimal pounds
L = Length in inches
G = Girth in inches (default is .58 * L)
R = 800 for trout/bass, 900 for pike/musky
