1. What is the Aquarium Gallon Calculator?

The Aquarium Gallon Calculator estimates the volume of water in a cylindrical aquarium based on its dimensions. It helps aquarium owners determine the appropriate amount of water needed and assists in calculating chemical dosages.

2. How Does the Calculator Work?

The calculator uses the cylindrical volume formula:

Where:

• \( r \) — Radius of the aquarium (inches)
• \( h \) — Height of the aquarium (inches)
• 231 — Cubic inches per US gallon

Explanation: The formula calculates the volume of a cylinder in cubic inches and converts it to US gallons.

3. Importance of Volume Calculation

Details: Knowing your aquarium's volume is essential for proper fish stocking, water treatment dosing, and equipment selection.

4. Using the Calculator

Tips: Measure the radius (half of diameter) and height of your aquarium in inches. Enter these values to calculate the volume in US gallons.

5. Frequently Asked Questions (FAQ)

Q1: What if my aquarium isn't cylindrical?
A: This calculator is for cylindrical tanks only. For rectangular tanks, use length × width × height / 231.

Q2: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders. Account for substrate and decorations by reducing the calculated volume by 10-15%.

Q3: Should I measure inside or outside dimensions?
A: Always measure inside dimensions (water volume) excluding the glass thickness.

Q4: What's the conversion factor 231?
A: 1 US gallon = 231 cubic inches, which is the standard conversion for liquid volume.

Q5: Can I use this for other cylindrical containers?
A: Yes, this works for any cylindrical container when you need to calculate liquid volume in US gallons.
