1. What is a Fish Tank Litre Calculator?

Definition: This calculator estimates the water volume of a rectangular fish tank in liters based on its dimensions in centimeters.

Purpose: It helps aquarium enthusiasts determine the appropriate water volume for proper fish stocking, filtration, and treatment dosing.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_L \) — Volume in liters
• \( L \) — Length of tank in centimeters
• \( W \) — Width of tank in centimeters
• \( H \) — Height of tank in centimeters

Explanation: The dimensions are multiplied to get cubic centimeters, then divided by 1000 to convert to liters (since 1 liter = 1000 cm³).

3. Importance of Accurate Volume Calculation

Details: Knowing your tank's exact volume is crucial for proper fish stocking levels, accurate medication dosing, and selecting appropriate filtration systems.

4. Using the Calculator

Tips: Measure the internal dimensions of your tank (excluding glass thickness) in centimeters. Enter all three dimensions for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: Why measure in centimeters?
A: The UK aquarium industry typically uses centimeters for tank measurements, and it provides precise volume calculations in liters.

Q2: Should I include the glass thickness in measurements?
A: No, measure only the internal water-holding space for accurate volume calculations.

Q3: How does substrate affect the volume?
A: Gravel or sand displaces water. For precise volume, measure height from substrate surface to tank rim.

Q4: What about irregularly shaped tanks?
A: This calculator is for rectangular tanks. For cylindrical tanks, use πr²h formula (divide by 1000 for liters).

Q5: Does this account for decorations and equipment?
A: No, the calculated volume is the maximum capacity. Actual water volume will be less when accounting for decor and equipment.
