Aquarium Calculator - Calculate Fish Tank VolumeCommon Aquarium Calculations
Below you will find our aquarium calculator that you can use to convert back and forth between some of the most common conversions you'll encounter when running your fish tank as well as a tool to calculate fish tank volume based on dimensions.
Currently, we have Fahrenheit to Celsius, Gallons to Liters, Inches to Centimeters (useful for determining fish species sizes), UK Gallons to US Gallons, and also a calculator to determine the total volume of your aquarium. Please note that the total tank volume figure computed is a rough estimate and only takes into account your fish tank dimensions. It does not take into account ornaments, decorations, the substrate, live rock, etc. These items can have an effect on the total volume of water in your aquarium. This calculation is simply based on an empty tank with the given dimensions.
*Numbers round up to two decimals places upon conversion.
