Fish keeping FAQs

Below you'll find answers to the questions we get asked the most about keeping fish.

How do I calculate the volume of my aquarium?

The length x depth x width in metres, multiplied by 1000 will give the volume in litres.

To work this out you might need to convert inches to cm, the equation for this is 1inch = 2.54cm. For example 12 inches x 2.54 = 30.48cm. 30.48 / 100 = size in metres.  

If you then want to convert the litres to US Gallons, multiply the volume in litres by 0.264.

For example: 20 litre aquarium 20 x 0.264 = 5.28 US Gallons
