Walleye Weight Conversion

What is the correct formula to convert walleye length and girth into pounds? It's not the same for pike and musky is it?

Thanks for the link but I want to put a spreadsheet together that has length across the horizontal axis and girth across the vertical axis. The calculation results will be displayed in the cells. I will print the sheet and have it laminated and keep it in the boat. I have done this for musky/pike weights. I read that the musky formula is L x (G x G)/800. Does anyone know if it is the same for walleye?

I posted this a few months ago and didn't receive any information. I can give you what I found.

The WC scale is unique and was told that it was formulated off the Western Walleye Calculator that is used by the Montana Walleye Circuit:

They have based these results off particular bodies of water in the western regions of the US.

There are two general calculators that I have found, the one that you mention: L x G x G / 800 (or 775). Another general one I see often is: L x L x L / 2700 (or 2300).

If you take a 31" fish w/ a 18" girth, you will get the following results:
WC = 12.13 lbs.
LxLxL/2700 = 11.03 lbs.
LxLxL/800 = 12.56 lbs.
Montana Walleye Circuit = 12.06 lbs.

So you can get a 1 1/2 lb variance depending on what calculator you use. From what I understand, the L x G x G / 800 is more suited for Walleye, Bass & Trout species while the L x L x L / 2700 is more suited to cylindrical species (muskie, pike, gars).

I had caught my largest walleye last fall. The digital weight scale I was using was off by 8.48% when I compared calibrated weights at room temperature and at 32 deg F. So I searched for some calculators to help me determine the fish's more realistic weight. I recorded the measurements from the some of the largest fish last year, and the L x G x G / 800 was the closest calculated weight formula.
