How to Use This Calculator

How the result changes with Length (inches)

Tank Shape: 1 = Rectangular, 2 = Cylinder, 3 = Bowfront.
Length (inches): Front-to-back length of the tank (or diameter for cylinder).
Width / Diameter (inches): Side-to-side width. For cylinders, this is the diameter.
Height (inches): Water fill height of the tank.

Volume (US gallons): Tank water volume in US gallons.
Volume (liters): Tank water volume in liters.
Water Weight (lbs): Weight of the water alone at 8.34 lbs/gallon.
Total Filled Weight (lbs): Estimated total weight including water, glass, and substrate. Your stand must support this.
Floor Load (lbs/sq ft): Weight per square foot of footprint. Standard residential floors support 40-50 lbs/sq ft.
Footprint (sq ft): Tank footprint area.

Calculate Volume
Volume = volumeCubicIn / 231
50.5 = 50.5
Calculate Total Filled Weight
Total Filled Weight = waterWeightLbs + glassWeight + substrateWeight
522.1 = 522.1
Calculate Volume
Volume = gallons * 3.78541
191.1 = 191.1
Calculate Water Weight
Water Weight = gallons * 8.34
421.1 = 421.1
