What is the Cylinder Volume Calculator?
The cylinder volume calculator gives the capacity and surface area of a cylinder, handy for tanks, pipes, cans and storage drums.
How to use the Cylinder Volume tool
- Enter Radius and Height.
- The result updates instantly as you type, or press Calculate.
- Use Try an example to see how it works, and Reset to start again.
Formula
Volume = π × r² × h. Lateral area = 2 × π × r × h. Total area = lateral + 2 × π × r².
Worked example
With radius 4, height 10, the volume comes to 502.6548. Lateral surface area: 251.3274; Total surface area: 351.8584.
Frequently asked questions
How do I convert volume to litres?
If your lengths are in centimetres, divide the cubic centimetres by 1000 to get litres.
What if I know the diameter?
Halve it to get the radius first.
