Cylinder Volume Formulas

Using Radius R and Length L

$$V = \pi \times R^2 \times L$$

Where V is volume, π ≈ 3.14159, R is radius, and L is length

Using Diameter D and Length L

$$V = \frac{\pi \times D^2 \times L}{4}$$

Where V is volume, π ≈ 3.14159, D is diameter, and L is length

FAQ

What is the difference between a cylinder and a tube?
A cylinder is a solid shape with circular cross-sections, while a tube is hollow with both inner and outer diameters. This calculator computes solid cylinder volume. For tubes, use the round tube calculator which accounts for wall thickness.
How do I measure cylinder dimensions accurately?
Use calipers to measure the diameter at several points along the length to ensure consistency. For the length, measure along the axis of the cylinder. For manufacturing parts, use precision measuring tools and take multiple measurements to account for any variations.
What are common applications for cylinder volume calculations?
Applications include calculating material quantities for rods and bars, determining capacity of cylindrical tanks, estimating volumes for pistons and shafts, calculating material weights for machining, and determining volumes for cylindrical containers or pipes.
Can I use this calculator for tapered cylinders or cones?
This calculator is for uniform cylinders with constant diameter only. For tapered cylinders or cones, you need different formulas. A cone volume is (1/3)πr²h, while tapered cylinders require integration or approximation methods.
How do I choose between radius and diameter input?
Use whichever measurement is easier to obtain. Diameter is often easier to measure directly with calipers, while radius might be given in technical drawings. The calculator handles both inputs and produces the same result.
What happens if my cylinder has rounded ends or is not perfectly straight?
This calculator assumes perfect cylindrical geometry with flat ends. For cylinders with rounded ends (like capsules), you'd need to add the volume of the spherical caps. For bent or irregular cylinders, the calculation becomes more complex and may require specialized methods.
