There is a calculator here somewhere on this site. A friend of mine used it to calculate my sons fish. It was a 42" x 28" girth King. This calculator makes it a 50+# king. It is way off. It weighed out after bled and sitting in the box all afternoon at 41 (certified scale). The PP calc showed it to be 42.5. Which should be right on. The bc one is off.
