Fish Tank Volume Formula:
From: | To: |
The fish tank volume formula calculates the capacity of an aquarium in US gallons. It uses the dimensions of the tank (length, width, and height) to determine how much water it can hold.
The calculator uses the formula:
Where:
Explanation: The formula calculates the cubic volume of the tank and converts it to US gallons (since 1 US gallon = 231 cubic inches).
Details: Knowing your fish tank's volume is essential for proper stocking levels, medication dosing, filter selection, and maintaining a healthy aquatic environment.
Tips: Measure the inside dimensions of your aquarium in inches. Enter length, width, and height values. All measurements must be greater than zero.
Q1: Why divide by 231 in the formula?
A: 231 is the conversion factor since 1 US gallon equals exactly 231 cubic inches.
Q2: Should I measure inside or outside dimensions?
A: Always measure the inside dimensions (water volume space) for accurate calculations.
Q3: How does substrate affect volume calculation?
A: Substrate reduces actual water volume. For precise measurements, account for substrate depth in your height measurement.
Q4: Can I use this for irregularly shaped tanks?
A: This formula works best for rectangular aquariums. Cylindrical tanks require a different formula (π × r² × h / 231).
Q5: How accurate is this calculation?
A: The calculation is mathematically precise but assumes perfect rectangular dimensions. Actual water volume may vary slightly due to tank construction.
