1. What is an Aquarium Volume Calculator?

Definition: This calculator estimates the water volume of an aquarium in gallons based on its dimensions in inches.

Purpose: It helps aquarium owners determine the proper water volume for fish stocking, filtration, and treatment dosing.

2. How Does the Calculator Work?

The calculator uses the formula:

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 product of the three dimensions gives cubic inches, which is then converted to gallons.

3. Importance of Accurate Volume Calculation

Details: Proper volume estimation ensures correct fish stocking levels, appropriate filter sizing, and accurate medication dosing.

4. Using the Calculator

Tips: Measure the interior dimensions of your aquarium (excluding glass thickness). Enter all dimensions in inches. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why use 231 in the formula?
A: 231 cubic inches equals 1 US gallon, the standard conversion factor.

Q2: Should I include the glass thickness?
A: No, use only the interior water space dimensions for accurate results.

Q3: What about irregularly shaped tanks?
A: For cylindrical tanks, use π × r² × H / 231. This calculator is for rectangular tanks only.

Q4: Does this account for substrate and decorations?
A: No, this calculates total volume. Subtract 10-20% for typical displacement.

Q5: How do I convert to liters?
A: Multiply gallons by 3.78541 to get liters.
