Aquarium Volume Formula:
| From: | To: |
The Aquarium Gallon Size Calculator estimates the volume of water an aquarium can hold based on its dimensions. This calculation is essential for proper fish stocking, filtration system selection, and water treatment planning.
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.
Details: Knowing your aquarium's exact volume is crucial for determining appropriate fish population, selecting the right size filter, calculating proper medication dosages, and planning water changes.
Tips: Measure the inside dimensions of your aquarium in inches. Enter length, width, and height. All values must be positive numbers. The result will show the total water volume in gallons.
Q1: Why measure inside dimensions instead of outside?
A: Inside dimensions give the actual water volume capacity, while outside dimensions include the thickness of the glass/acrylic.
Q2: Does this account for substrate and decorations?
A: No, this calculates total volume. For actual water volume, subtract space taken by substrate, rocks, and decorations (typically 10-20%).
Q3: What's the conversion factor 0.00433?
A: This converts cubic inches to US gallons (1 gallon = 231 cubic inches, so 1/231 ≈ 0.004329).
Q4: Can I use this for irregularly shaped aquariums?
A: This formula works for rectangular tanks. For bow-front, cylindrical, or hexagonal tanks, specialized formulas are needed.
Q5: How accurate is this calculation?
A: Very accurate for rectangular aquariums when using precise measurements. Always consider leaving some headspace for water displacement.
