Cylinder Volume Calculator
Calculate the volume of a cylinder from its base radius and height — get the result instantly.
Formula
V = π · r² · h
where r is the base radius and h is the height of the cylinder
About the Cylinder Volume Calculator
A cylinder is a 3D shape with two identical circular bases and a curved surface between them. Its volume tells you how much it can hold inside.
To find the volume of a cylinder, multiply the base area (π·r²) by the height. This is useful for barrels, pipes, tanks, and containers.
All calculations run instantly and locally in your browser — nothing is uploaded, keeping your numbers completely private.

Frequently Asked Questions
How do you calculate the volume of a cylinder?
Multiply the base area by the height: V = π·r²·h. For example, a radius of 2 cm and height of 10 cm give a volume of about 125.66 cm³.
What is the formula for the volume of a cylinder?
The cylinder volume formula is V = π·r²·h, where r is the base radius, h is the height, and π ≈ 3.14159.
What if I know the diameter instead of the radius?
The radius is half the diameter: r = d/2. Find the radius first, then plug it into the formula.
What units does the volume come out in?
Volume is measured in cubic units. If you entered the radius and height in centimeters, the result is in cubic centimeters (cm³).
How do I convert the volume to liters?
One liter equals 1000 cm³. To get liters, divide the volume in cubic centimeters by 1000.
