Cylinder Volume Calculator Formula
Volume of a cylinder:
V = π × r² × h
r = radius, h = height
How to Use This Calculator
- Enter the radius of the circular cross-section.
- Enter the height of the cylinder.
- Click Calculate Volume to see the result.
Frequently Asked Questions
What if I only know the diameter?
The radius is half the diameter: r = diameter / 2. Divide your diameter by 2 before entering it here.
How do I find the volume of a tank or pipe?
For a cylindrical tank, measure the inner radius and height (or depth of water), then use V = πr²h. For a hollow pipe, use our tube volume calculator instead.
What units does this calculator use?
This calculator is unit-agnostic. If you enter radius in meters and height in meters, the result is in cubic meters (m³). Always use the same unit for both inputs.
How do I convert cubic units to liters or gallons?
One liter equals 1,000 cm³, and one US gallon equals 3,785.41 cm³. Calculate the cylinder volume in centimeters, then divide by 1,000 for liters or by 3,785.41 for US gallons.
What is the surface area of a cylinder?
The total surface area is SA = 2πr² + 2πrh. The first term covers the two circular end caps, and the second term covers the curved lateral surface.
Can I share my calculation?
Yes. After clicking Calculate, the URL updates with your input values. Copy and share the URL to let anyone else see the same pre-filled form and result.
