This website has two good options which make it a bit better than above mentioned website. It provides a sample image for all the types of aquariums for which it can provide the output. Another option is that the output is generated automatically. You don’t need to use calculate or some other button.
When you add fish tank length, one side length (for hexagon aquarium), tank height, etc., then the output calculation is generated immediately. The output shows aquarium volume in US and UK gallons and liters.
Amazing Amazon
Amazing Amazon has also reserved its place on this list. It lets you calculate volume for:

A diagram is also provided for any of the tank selected by you. Once you’ve selected the tank type and updated it, you can add tank side, water depth, filter volume, tank width, tank length, etc., depending on the selected tank, and you can get the output. The result shows total water volume in liters.
The best part is it also provides the suggestions that you should have minimum weight of calgrit, salt, etc., to get sufficient amount of depth for the tank size specified by you.
Aquarium Dimensions
Aquarium Dimensions has one unique feature which catches the attention. Its link is here. You can set quantity (number of fish tanks) and get the output for all those tanks. It lets you set tank height, length, and width, and then you can calculate the output for one or number of aquariums set by you. It also provides estimated price for glass aquariums empty for a 10 gallon and 400 pounds empty for a 265 gallon. This will be helpful as you can have an idea before buying an aquarium.
The result will show you tank volume in liters and US gallons. It doesn’t come with options to calculate volume for hexagon fish tank or cylinder aquarium. It is mainly useful to calculate the volume of rectangle fish tank. This is all this website does. If you need a simpler aquarium volume calculator, then this website deserves a try.
The Conclusion:
These are the best free online aquarium volume calculator websites covered by us. All are really good to find out tank volume and some are more useful because those support different aquarium shapes. Among all these aquarium volume calculators, my favorite on this list is “Omnicalculator“.
