Aquarium Volume Formula:
| From: | To: |
The Aquarium Tank Size Calculator estimates the water volume in US gallons for rectangular aquariums based on length, width, and height measurements. This helps aquarists determine appropriate tank capacity for fish stocking and maintenance.
The calculator uses the standard aquarium volume formula:
Where:
Explanation: The formula calculates the internal volume in cubic inches and converts it to US gallons using the standard conversion factor.
Details: Accurate volume calculation is essential for proper fish stocking levels, determining filter capacity, calculating medication dosages, and planning water change schedules.
Tips: Enter all dimensions in inches. Measure the internal dimensions of the aquarium for most accurate results. All values must be positive numbers.
Q1: Why use 0.00433 as the conversion factor?
A: This factor converts cubic inches to US gallons (1 gallon = 231 cubic inches, so 1/231 ≈ 0.004329).
Q2: Should I include substrate and decorations in my calculations?
A: For water volume calculations, subtract the space taken by substrate and decorations. For fish stocking calculations, use total volume.
Q3: What's the difference between US gallons and imperial gallons?
A: US gallons are smaller (3.785 liters) than imperial gallons (4.546 liters). This calculator uses US gallons.
Q4: How accurate is this calculation for curved or bow-front aquariums?
A: This formula is designed for rectangular tanks. For curved or irregular shapes, specialized formulas or water displacement methods are more accurate.
Q5: Can I use this for saltwater aquariums?
A: Yes, the volume calculation is the same, but remember that saltwater setups often require more consideration for equipment space and water displacement.
