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 enthusiasts determine the water capacity of their tanks for proper fish stocking and equipment sizing.

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 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 all dimensions in inches. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 231 cubic inches per gallon?
A: This is the standard conversion factor (1 US gallon = 231 cubic inches) established by US liquid measures.

Q2: What if my tank isn't rectangular?
A: This calculator is for rectangular tanks only. Different formulas are needed for cylindrical, bow-front, or other shapes.

Q3: Should I include the glass thickness in measurements?
A: No, measure only the interior water-holding space for accurate volume calculations.

Q4: Does this account for substrate and decorations?
A: No, this calculates total volume. For actual water volume, subtract space taken by substrate, rocks, and decorations.

Q5: How do I convert to liters?
A: Multiply gallons by 3.78541 to get liters (1 US gallon = 3.78541 liters).
