Formula and methodology
Formula: Estimated mass = coefficient×length×girth².
The coefficient is deliberately visible so the visitor can replace it with a documented species or local convention rather than receiving an unexplained universal constant.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Fish length — cm; minimum 1.0E-6; maximum 1000000
- Fish girth — cm; minimum 1.0E-6; maximum 1000000
- Entered weight coefficient — kg/cm³; minimum 1.0E-12; maximum 1000
Worked example
| Input | Value |
|---|---|
| Fish length | 60 |
| Fish girth | 35 |
| Entered weight coefficient | 0.0001 |
Estimated mass = 7.35 kg.
Assumptions and limits
- Length and girth are centimetres and the coefficient is compatible with those units.
- The model is an entered empirical estimate, not a biological measurement law.
- Species, body shape, condition, uncertainty, handling, and conservation rules are not inferred.
