Calculate aquarium volume in gallons and liters from tank dimensions. Rectangular, bowfront, and cylindrical tanks.
In this article
Formula
L × W × H (cm) / 1000 = litres। 60×30×35 = 63 litres। Full weight: 63 kg + gravel + glass = 75+ kg। Check furniture strength! Real volume 10-15% less (substrate/decor)।
Starter
Minimum 60 litres। Sobo, Sunsun: affordable Indian brands। Guppies, Mollies, Tetras: easy beginners।
⚡ CalcWolf Insight
Subtract 10-15% from your calculated volume for the "real" water volume after substrate, rocks, wood, and equipment displace water. A 20-gallon tank with 2 inches of gravel and a few decorations holds about 17-18 gallons of actual water.
