Aquarium Volume Formula:
| From: | To: |
The Aquarium Gallon Size Calculator estimates the volume of an aquarium in US gallons based on its dimensions. This calculation is essential for proper fish stocking, filtration system selection, and water treatment dosing.
The calculator uses the standard volume formula:
Where:
Explanation: The formula calculates the cubic volume of the aquarium 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 capacity, calculating correct medication dosages, and maintaining optimal water quality parameters.
Tips: Measure the inside dimensions of your aquarium in inches. Enter length, width, and height as decimal numbers. All values must be positive numbers greater than zero.
Q1: Why use 231 as the conversion factor?
A: 231 cubic inches equals exactly one US gallon, which is the standard conversion used in the aquarium industry.
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: How does aquarium shape affect the calculation?
A: This calculator assumes a rectangular aquarium. For cylindrical, bow-front, or other shaped tanks, different formulas are needed.
Q4: Does this account for substrate and decorations?
A: No, this calculates total volume. Actual water volume will be less due to substrate, rocks, and decorations displacing water.
Q5: Can I use this for saltwater aquariums?
A: Yes, the volume calculation is the same for freshwater and saltwater aquariums, though stocking guidelines differ.
