Aquarium Volume Calculator
Easily calculate the water volume of your aquarium in liters and gallons by entering its length, width, and height.
Volume (Liters) = (Length × Width × Height) / 1000 1 Liter = 0.264172 US Gallons
Volume calculations used in this tool are based on standard aquarium industry practices (L x W x H) and estimated net volume losses based on Archimedes' principle.
Calculations are based on mathematical formulas and show approximate values. They are for informational purposes only. It is recommended to research the net amount of water required for your livestock species.
Frequently Asked Questions
What is net and gross aquarium volume?
Gross volume is the total space calculated with the external dimensions of the aquarium. Net volume is the actual amount of water the aquarium can hold after adding glass thickness, sand, rocks, filters, and other decorations.
How many gallons is 1 liter of water?
1 liter of water is approximately equal to 0.264172 US gallons. In Imperial gallon calculation, the ratio is approximately 0.219969.
How do I find the net water volume of my aquarium?
To find the actual (net) water volume, it is recommended to subtract a value of about 10-20% (depending on the amount of decoration and sand used) from the calculated gross volume.
