1. What is an Aquarium Volume Calculator in Gallons?

Definition: This calculator estimates the water volume of an aquarium in gallons based on its length, width, and height measurements in inches.

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

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

Explanation: The formula converts cubic inches to gallons (1 gallon = 231 cubic inches).

3. Importance of Aquarium Volume Calculation

Details: Accurate volume measurement ensures proper fish stocking levels, correct medication dosing, and appropriate filter selection.

4. Using the Calculator

Tips: Measure the inside dimensions of your aquarium in inches. Enter length, width, and height. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why measure in inches?
A: The formula uses inches because 1 gallon equals exactly 231 cubic inches, making calculations precise.

Q2: Should I include the aquarium thickness?
A: No, use only the interior dimensions where water will be.

Q3: What about irregularly shaped tanks?
A: For cylindrical tanks, use πr²h/231. For bow-front tanks, use approximate measurements.

Q4: Does this account for substrate and decorations?
A: No, this calculates total volume. Subtract 10-20% for actual water volume with substrate and decor.

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