Got a new tank at the weekend (won it on Ebay), and silly me when i was filling it didn't count the liters!!!
it measures;

31 cm width 37 cm height and 91 cm length, any ideas???

congrats on your new tank!

by your measurements, id say your tank is about 22-25 gallons. the numbers arent exactly standard sizes so, i could be off by a gallon or two.

hope this helps!

thanks very much, used the conversion page, makes it approx 90 liters.... and that's what i thought it looked like (compared to the 30 liter one i already have).

Ta very much.....

Hi to calculate the volume in liters you just need mutiply the numbers in meters.
volume= 0,31x0,37x0,91
volume = 0,104377 cubic meters. Than you move the coma 3 times.
1 cubic meter = 1000 liters
volume = 104,377 liters.

So, your tank has 104,37 liters
