Girth & Length are Inches

Lbs.

Example: If the fish’s girth is 15 inches and its length is 29 inches, the formula would be used as follows: 15 x 15 x 29, divided by 800 = 8.16 pounds

IGFA Fish Weight Formula: ((Girth x Girth) x Length) / 800 = weight in pounds

Then the ".16" or "16/100" is converted to ounces (multiply by 16) .16 x 16 = 2.56 or 3 ounces so this fish is 8 pounds 3 ounces
