Calculate capsule, pill or spherocylinder volume from radius, diameter, cylindrical height or total length, with reverse solving.
This calculator finds the volume of a capsule from the radius or diameter and the cylindrical height or the total length. It works for capsule, pill, and spherocylinder shapes.
volume of a capsule
radius or diameter
cylindrical height
total length
The calculator can also work in reverse when the volume is already known and you want to solve for a missing radius, diameter, height, or length. This is useful in geometry, 3D modelling, and technical calculations.
$$V= \pi r^2\left(h+\frac{4r}{3}\right)$$
A capsule volume is the sum of a cylinder and two hemispheres. This calculator applies the correct formula automatically from the radius or diameter together with the cylindrical height or total length.
You can use radius and cylindrical height, radius and total length, diameter and cylindrical height, or diameter and total length. That makes it useful for capsules, pills, and spherocylinder shapes.
Yes. If the capsule volume is already known, the calculator can reverse solve for a missing radius, diameter, cylindrical height, or total length.
It is useful for geometry, industrial design, packaging, 3D modeling, medical or pill-shaped parts, and any estimate involving a rounded-end cylinder.
