How Big Is My Aquarium In Gallons?
I got an aquarium at a thrift store and it wasn't labeled. I measured it and it measures 19Lx12Wx12H. What is the size in gallons? Thank you.

1 cubic inch = .0043 gallons. therefore your tank being 19 x 12 x 12 is 2736 cubic inches. 2736 x .0043 is 11.7648 gallons. Your tank is 12 gallon tank.
I’m not sure if you’re measurements are in inches or centimeters but if it’s inches: 11.84 US gallons
11.84g so 12g pretty much!!
11.84688gal.
