1. What is a Fish Tank Volume Calculator?

Definition: This calculator estimates the volume of a fish tank in gallons based on its dimensions in inches.

Purpose: It helps aquarium hobbyists determine the water capacity of their tanks for proper fish stocking and equipment selection.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_{gal} = \frac{L \times W \times H}{231} \]

Where:

\( V_{gal} \) — Volume in gallons
\( L \) — Length in inches
\( W \) — Width in inches
\( H \) — Height in inches
231 — Cubic inches per gallon conversion factor

Explanation: The tank's dimensions are multiplied together to get cubic inches, then divided by 231 to convert to gallons.

3. Importance of Tank Volume Calculation

Details: Knowing your tank's volume is crucial for proper fish stocking levels, medication dosing, filter selection, and heater sizing.

4. Using the Calculator

Tips: Measure the inside dimensions of your tank (excluding glass thickness). Enter length, width, and height in inches. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231?
A: There are exactly 231 cubic inches in one US gallon, which is the standard conversion factor.

Q2: Should I include the glass thickness?
A: No, measure only the internal dimensions where water will be.

Q3: What about irregularly shaped tanks?
A: This calculator is for rectangular tanks. For other shapes, use specialized formulas.

Q4: Does this account for substrate and decorations?
A: No, this calculates total volume. Subtract about 10-15% for displacement by gravel, rocks, etc.

Q5: How accurate is this calculation?
A: Very accurate for rectangular tanks when proper measurements are taken.
