Volume is length times width times water depth, divided by 1,000 for liters when measured in centimeters. A liter of water weighs a kilogram, so a 60 liter tank weighs over 60 kg before glass and substrate, which is why stands must be rated for the filled weight.
Heaters are sized at about 5 watts per gallon for rooms near normal temperature, and filters should turn over 4 to 6 times the tank volume per hour. Cold rooms need more heater wattage, and messy fish like goldfish need stronger filtration.
