How to Use the Calculator

  1. Enter the length of the bass fish in inches. This is required.
  2. Optionally, enter the girth (circumference) of the bass in inches for a more accurate estimate.
  3. Click the "Calculate" button to estimate the weight.
  4. The estimated weight will be displayed in pounds.

Understanding the Formula

The calculator uses the following formula to estimate bass weight:

Weight (lbs) = Length² × Girth² × 0.0043

This formula is a standard approximation for largemouth bass and provides a reasonable estimate when exact scale weight is not available.

Usage Tips

  • For the most accurate results, use a measuring tape to measure both the length (from the tip of the nose to the end of the tail) and the girth (the circumference of the thickest part of the fish).
  • This calculator is best used for estimating weight in fishing competitions or record keeping where exact weight is not available.
  • The accuracy of the estimate depends on the accuracy of the length and girth measurements.
