Northern Pike Length to Weight Conversions

The obvious way to determine the weight of your pike is to weigh it, using a weighing sling and scale.

If you do not have a scale but know the length and girth of your pike you can calulate it's 
approximate weight based on a couple different widely accepted formulas:


Formula 1:  length (in.) x girth (in.) x girth (in.) / 800 = weight (lbs.)

Formula 2 (The Crawford Method):  [length (in.) x girth (in.)/25] - 25 = weight (lbs.)


We have provided printable tables based on Formula 1:


The following table shows weights using Formula 2:
