UK Metric Formula:
| From: | To: |
The Fish Tank Capacity Calculator helps aquarium enthusiasts determine the volume of their fish tank using the standard UK metric formula. This calculation is essential for proper fish stocking, water treatment, and equipment selection.
The calculator uses the UK metric formula:
Where:
Explanation: This formula converts the cubic centimeter measurement of the tank's volume into litres, which is the standard unit for aquarium measurements in the UK.
Details: Knowing your tank's exact volume is crucial for determining the appropriate number of fish, calculating correct medication dosages, selecting properly sized filters and heaters, and maintaining optimal water quality.
Tips: Measure the internal dimensions of your tank in centimeters. Enter the length, width, and height measurements. All values must be positive numbers. For irregularly shaped tanks, calculate the volume of different sections separately and add them together.
Q1: Why measure internal dimensions instead of external?
A: Internal dimensions give the actual water volume, while external measurements include the thickness of the glass/acrylic, which doesn't hold water.
Q2: How does substrate affect volume calculation?
A: Gravel, sand, and decorations displace water. For more accuracy, subtract approximately 10-15% from the calculated volume if you have significant substrate.
Q3: Can I use this calculator for cylindrical tanks?
A: No, this calculator is for rectangular tanks. For cylindrical tanks, use the formula: π × radius² × height / 1000.
Q4: Why is volume important for fish stocking?
A: Different fish species require specific amounts of water per fish for healthy living. Overstocking can lead to poor water quality and stressed fish.
Q5: How often should I recalculate my tank volume?
A: Only when you change your tank setup significantly, such as adding a lot of new decorations or changing substrate depth.
