Enter the length and girth of the trout into the calculator to determine the weight.

## Trout Weight Formula

The following formula is used to calculate the weight of a trout.

W = (L^3 * G) / 800

Variables:

- W is the weight of the trout (lbs) L is the length of the trout (inches) G is the girth of the trout (inches)

To calculate the weight of a trout, cube the length of the trout, then multiply the result by the girth of the trout. Divide the result by 800 to get the weight of the trout in pounds.

## What is a Trout Weight?

A trout weight refers to the mass or heaviness of a trout, a type of freshwater fish. It is often used by anglers and fisheries to determine the health, age, and maturity of the fish. The weight of a trout can vary greatly depending on its species, diet, habitat, and other factors. It is typically measured in pounds or kilograms.

## How to Calculate Trout Weight?

The following steps outline how to calculate the Trout Weight using the given formula:

- First, determine the length of the trout (L) in inches.
- Next, determine the girth of the trout (G) in inches.
- Next, calculate L^3 (L cubed).
- Then, multiply L^3 by G.
- Finally, divide the result by 800 to calculate the weight of the trout (W).

**Example Problem:**

Use the following variables as an example problem to test your knowledge:

Length of the trout (L) = 20 inches

Girth of the trout (G) = 12 inches
