Cylinder Volume Calculator – Accurately Measure Cylinder Capacity

The Cylinder Volume Calculator is a practical and easy-to-use tool designed for engineers, students, construction professionals, and anyone who needs to compute the volume of a cylinder.

Formula

Volume = π × r² × h

How to Use

  1. Enter the radius (half the diameter) and height in the same unit.
  2. Click Calculate to see volume and base area.
  3. Click Copy Result to copy the output.

Example Calculations

r = 4 cm, h = 10 cm → V = π × 16 × 10 ≈ 502.65 cm³

r = 1.5 m, h = 5 m → V = π × 2.25 × 5 ≈ 35.34 m³

Working with Diameter

r = diameter / 2. For diameter = 8 cm, use r = 4 cm.

Frequently Asked Questions

Can I enter diameter instead of radius?

Divide diameter by 2 first, then enter as radius.

Is there a formula for hollow cylinders?

V = π × (R² − r²) × h, where R = outer radius, r = inner radius.

What units does the result use?

Cubic units matching your input — cm → cm³, m → m³, ft → ft³.

How precise is the result?

The calculator uses JavaScript's full-precision Math.PI ≈ 3.141592653589793.

What is the surface area formula?

Surface Area = 2πr² + 2πrh.
