1. What Is This Calculator For?

This calculator helps you determine the volume of your fish tank in gallons based on its dimensions. Knowing your tank's exact size is crucial for proper fish stocking, filtration, and maintenance.

2. How Does The Calculator Work?

The calculator uses the standard volume formula:

Where:

• \( Length \) — Tank length in inches
• \( Width \) — Tank width in inches
• \( Height \) — Tank height in inches
• 231 — Cubic inches per gallon conversion factor

Explanation: The formula calculates cubic inches first, then converts to gallons (since 1 gallon = 231 cubic inches).

3. Importance Of Knowing Your Tank Size

Details: Accurate tank volume is essential for determining appropriate fish population, medication dosing, filter capacity, and heater requirements.

4. Using The Calculator

Tips: Measure inside dimensions (excluding glass thickness) for most accurate results. For irregular shapes, measure average dimensions.

5. Frequently Asked Questions (FAQ)

Q1: Why measure in inches?
A: The standard gallon conversion uses inches. For centimeters, divide by 3785.41 (cubic cm per gallon) instead.

Q2: What about bow-front or cylindrical tanks?
A: This calculator is for rectangular tanks. Special formulas exist for other shapes.

Q3: Does substrate affect the calculation?
A: Yes, subtract substrate depth from height if calculating actual water volume.

Q4: What's a typical home aquarium size?
A: Common sizes range from 10-55 gallons for beginners, with 20-29 gallons being most popular.

Q5: How accurate is this calculation?
A: Very accurate for rectangular tanks. Account for decorations/equipment that displace water.
