Calculate the volume of liquid in vertical and horizontal cylindrical tanks. Perfect for fuel storage, water tanks, and industrial applications.
A cylindrical tank is a storage vessel with a circular cross-section and uniform diameter along its length. These tanks are among the most common storage solutions due to their structural efficiency, ease of manufacturing, and optimal strength-to-weight ratio.
Choose whether your tank is vertical (upright) or horizontal (on its side)
Input the tank's diameter (or radius), length/height, and current liquid depth
View the calculated volume in multiple units including gallons, liters, and cubic feet
V = πr²h
Vliquid = πr²hliquid
Where: r = radius, h = total height, hliquid = liquid height
A = r² arccos((r-d)/r) - (r-d)√(2rd-d²)
Vliquid = A × L
Where: r = radius, d = liquid depth, L = tank length, A = circular segment area
Given:
Calculation:
Vliquid = π × 2² × 6 ≈ 75.4 cubic feet
Converting: 75.4 × 7.48 ≈ 564 gallons
Given:
Result:
Using circular segment formula:
Liquid volume ≈ 628 cubic feet ≈ 4,697 gallons
