Aquarium Volume Formula:
| From: | To: |
Aquarium volume calculation determines the water capacity of a rectangular aquarium in gallons. This is essential for proper fish stocking, filtration system selection, and water treatment dosing.
The calculator uses the standard aquarium volume formula:
Where:
Explanation: The formula calculates the cubic volume in 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 population, selecting proper filtration capacity, calculating medication doses, and maintaining water quality parameters.
Tips: Measure the internal dimensions of your aquarium (length, width, height) in inches. Enter all measurements for accurate results. Remember to measure from the inside of the glass, not the outside dimensions.
Q1: Why use 231 as the conversion factor?
A: 231 cubic inches equals 1 US gallon, which is the standard conversion used in aquarium calculations in the United States.
Q2: Should I include substrate and decorations in my calculations?
A: For water volume only, subtract the space taken by substrate and decorations. For total capacity, use full internal dimensions.
Q3: How accurate is this calculation for irregular-shaped aquariums?
A: This formula is designed for rectangular aquariums. For bow-front, hexagonal, or cylindrical tanks, different formulas are required.
Q4: Does this work for saltwater aquariums?
A: Yes, the volume calculation is the same for both freshwater and saltwater aquariums, though water weight and specific gravity differ.
Q5: How much should I reduce volume for equipment and decorations?
A: Typically reduce calculated volume by 10-15% to account for substrate, rocks, and equipment displacement.
