Enter the capsule radius (in) and the capsule side length (in) into the Capsule Volume Calculator. The calculator will evaluate and display the Capsule Volume. 

Capsule Volume Formula

The following formula is used to calculate the Capsule Volume. 

Vc = pi*r^2*((4/3)*r+a)

  • Where Vc is the Capsule Volume (in^3)
  • r is the capsule radius (in) 
  • a is the capsule side length (in) 

How to Calculate Capsule Volume?

The following example problems outline how to calculate Capsule Volume.

Example Problem #1:

  1. First, determine the capsule radius (in). 
    1. The capsule radius (in) is given as: 30.
  2. Next, determine the capsule side length (in). 
    1. The capsule side length (in) is provided as: 20.
  3. Finally, calculate the Capsule Volume using the equation above: 

Vc = pi*r^2*(4/3*r+a)

The values given above are inserted into the equation below:

Vc = pi*30^2*(4/3*30+20) = 169,646 (in^3)


Example Problem #2: 

The variables needed for this problem are provided below:

capsule radius (in) = 50

capsule side length (in) = 60

Entering these values and solving gives:

Vc = pi*50^2*((4/3*50)+60) = 994,837.67 (in^3)
