Fish Tank Volume Formula:
| From: | To: |
The Fish Tank Volume Calculator calculates the water capacity of an aquarium in US gallons based on its dimensions. This is essential for proper fish stocking, filtration setup, and water treatment.
The calculator uses the standard aquarium volume formula:
Where:
Explanation: The formula calculates the cubic volume of the tank and converts it to US gallons using the standard conversion factor of 231 cubic inches per gallon.
Details: Accurate volume calculation is crucial for determining appropriate fish stocking levels, selecting proper filtration systems, dosing water treatments correctly, and maintaining healthy aquatic environments.
Tips: Measure the inside dimensions of your aquarium in inches. Enter length, width, and height. All values must be positive numbers. The result will be displayed in US gallons.
Q1: Why use 231 as the conversion factor?
A: 231 cubic inches equals 1 US gallon, which is the standard conversion used in the United States for liquid volume measurements.
Q2: Should I measure inside or outside dimensions?
A: Always measure inside dimensions (water space) for accurate volume calculation, as glass thickness reduces actual water capacity.
Q3: How does substrate affect tank volume?
A: Gravel, sand, and decorations displace water, reducing actual water volume. The calculated volume represents maximum capacity without substrate.
Q4: Can I use this for irregularly shaped tanks?
A: This calculator is designed for rectangular tanks. For cylindrical, bow-front, or other shapes, different formulas are required.
Q5: How accurate is this calculation?
A: The calculation is mathematically precise for the given dimensions. Actual water volume may be slightly less due to equipment, substrate, and not filling to the very top.
