Aquarium Volume Formula:
| From: | To: |
The aquarium volume calculation determines the water capacity of an aquarium in gallons based on its dimensions. This is essential for proper stocking, filtration, and maintenance of aquatic environments.
The calculator uses the aquarium volume formula:
Where:
Explanation: The formula calculates the volume in cubic inches and converts it to 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 medications and water treatments correctly, and maintaining optimal water quality.
Tips: Measure the interior dimensions of your aquarium in inches. Enter length, width, and height. All values must be positive numbers. The result will show the total water capacity in gallons.
Q1: Why divide by 231?
A: 231 cubic inches equals 1 US gallon, which is the standard conversion factor for volume calculations.
Q2: Should I measure inside or outside dimensions?
A: Always measure inside dimensions for accurate water volume calculation, as glass thickness reduces actual water capacity.
Q3: Does this account for substrate and decorations?
A: No, this calculates total volume. Actual water volume will be less due to substrate, decorations, and equipment displacement.
Q4: What's the difference between US gallons and imperial gallons?
A: US gallons (231 cubic inches) are used in this calculator. Imperial gallons are larger (277.42 cubic inches) and used in the UK.
Q5: How accurate is this calculation for irregular-shaped aquariums?
A: This formula is for rectangular aquariums. For bow-front, hexagonal, or cylindrical tanks, specialized formulas are needed.
