About the Water Tank Volume Calculator
Convert simple tank dimensions into three common capacity units.
Formula
Rectangular volume is length times width times height. Cylindrical volume is pi times radius squared times height.
Example
A 2 m by 1.5 m by 1.2 m rectangular tank has a geometric volume of 3.6 m³ or 3,600 liters.
Notes
The result does not subtract wall thickness, freeboard, fittings, internal structures or unusable capacity.
