How to Calculate Tank Volume
What is Tank Volume?
A tank volume calculator finds the volume of cylindrical, rectangular, oval, or conical tanks. Volume determines storage capacity for water, fuel, chemicals, or septic systems. Results are given in gallons, liters, and cubic feet.
Step-by-Step Guide
- 1Cylindrical: V = π × r² × h
- 2Rectangular: V = L × W × H
- 3Oval (elliptical): V = π × a × b × h (a,b = semi-axes)
- 4Conical: V = (1/3) × π × r² × h
- 51 cubic foot = 7.481 US gallons = 28.317 liters
Worked Examples
Input
Cylinder tank r=0.5 m · h=2 m
Result
Volume = π × 0.25 × 2 ≈ 1.57 m³ ≈ 1,570 litres
