Aquarium Volume Formula:
| From: | To: |
Aquarium volume calculation determines the water capacity of a fish tank in gallons. This 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 internal volume in cubic inches and converts to gallons using the standard conversion factor of 231 cubic inches per gallon.
Details: Correct tank sizing ensures adequate space for fish, proper water quality maintenance, appropriate filtration capacity, and accurate medication dosing for aquatic health.
Tips: Measure the internal dimensions of your aquarium in inches. Enter length, width, and height. All values must be positive numbers for accurate calculation.
Q1: Why use 231 as the conversion factor?
A: 231 cubic inches equals 1 US gallon, which is the standard conversion used in aquarium volume calculations.
Q2: Should I include substrate and decorations in my calculations?
A: For water volume only, subtract space taken by substrate and decorations. For total tank capacity, use full internal dimensions.
Q3: What's the difference between US gallons and imperial gallons?
A: US gallons (231 in³) are smaller than imperial gallons (277.42 in³). This calculator uses US gallons standard in aquarium keeping.
Q4: How accurate is this calculation for curved or irregular tanks?
A: This formula works best for rectangular tanks. For curved or irregular shapes, specialized formulas or water displacement methods are more accurate.
Q5: Why is knowing tank volume important for fish health?
A: Proper volume ensures adequate swimming space, maintains stable water parameters, and allows correct dosing of water treatments and medications.
