Volume Formula:
From: | To: |
Fish tank volume calculation determines the water capacity of a rectangular aquarium. Knowing the exact volume is essential for proper fish stocking, filtration setup, and water treatment dosing.
The calculator uses the standard volume formula for rectangular tanks:
Where:
Explanation: The formula calculates the cubic volume and converts it from cubic centimeters to litres (1 litre = 1000 cm³).
Details: Accurate volume calculation is crucial for determining appropriate fish population, selecting proper filter size, calculating correct medication doses, and maintaining optimal water quality.
Tips: Measure the internal dimensions of your tank (excluding glass thickness). Enter all measurements in centimeters. Ensure all values are positive numbers for accurate calculation.
Q1: Why measure internal dimensions only?
A: External measurements include glass thickness, which doesn't contribute to water volume. Always measure the actual water space inside the tank.
Q2: How does substrate affect volume?
A: Gravel, sand, and decorations reduce actual water volume. For precise calculation, subtract the volume occupied by substrate and decorations.
Q3: What's the difference between US gallons and litres?
A: 1 US gallon = 3.785 litres. This calculator provides results in litres, which is the standard metric unit for aquarium volume.
Q4: Can this calculator be used for irregular-shaped tanks?
A: No, this calculator is designed for rectangular tanks only. Irregular shapes require different calculation methods.
Q5: Why is accurate volume important for fish keeping?
A: Proper fish stocking (1 cm of fish per litre is a general guideline), correct filter sizing, and accurate medication dosing all depend on knowing the exact water volume.
