Capsule Volume Calculator
Calculate the volume of a capsule using its radius and straight length.
What is a Capsule?
A cylinder capped by two hemispheres.
A capsule is a basic three-dimensional geometric shape consisting of a cylinder with hemispherical ends. It is commonly seen in pill capsules and certain pressure vessels.
How to Find Capsule Volume
A capsule's volume is the sum of a cylinder and a sphere.
Capsule Volume Formula
The combined equation for a capsule.
Where 'r' is the radius and 'a' is the length of the straight cylindrical section.

Frequently Asked Questions
Can I just use the total length of the capsule?
Yes, but the formula changes slightly. If 'L' is total length, the straight part 'a' is equal to L × 2r.
Why does the formula include 4/3?
Because the two ends of the capsule form a complete sphere, and the formula for a sphere's volume includes the fraction 4/3.
Are medicine pills perfect capsules?
Usually yes, many medicinal pills are manufactured in standard geometric capsule shapes for easy swallowing.
What if the two ends have different radii?
Then it is not a standard capsule. You would have to calculate the volume of each hemisphere separately and add them to a conical frustum.
