1. What is an Aquarium Tank Gallon Calculator?

Definition: This calculator estimates the water volume in gallons for rectangular aquarium tanks based on their dimensions.

Purpose: It helps aquarium hobbyists determine how much water their tank can hold, which is crucial for proper filtration and fish stocking.

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 of tank (inches)
\( W \) — Width of tank (inches)
\( H \) — Height of tank (inches)
231 — Cubic inches per gallon conversion factor

Explanation: The formula calculates the cubic inches of the tank then converts to gallons (since 1 gallon = 231 cubic inches).

3. Importance of Accurate Volume Calculation

Details: Knowing your tank's exact volume is essential for proper medication dosing, fish stocking levels, and selecting appropriate filtration systems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why use 231 cubic inches per gallon?
A: This is the standard US gallon volume conversion (1 US gallon = 231 cubic inches).

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

Q3: How do I calculate for cylindrical tanks?
A: Use the formula: (π × radius² × height) / 231 where radius = diameter/2.

Q4: Does this account for substrate and decorations?
A: No, this calculates total volume. Actual water volume will be less when accounting for these items.

Q5: How accurate is this calculation?
A: Very accurate for rectangular tanks when using precise interior measurements.
