1 gallon is almost 3,8 liters, so 10 gallon tank would be 38 liters etc..
I had similar problem other way around =)
I you wanna know how many liters from the measurements in cm, just multiply all together and divide it by 1000..
example: 60cm x 45cm x 90cm = 243000 cm3 = 243 liters = 64 gallons
..now, I guess they don't calculate the full measurements, so this one would be 60 gallon tank![]()
