Geometry Tool
Capsule Calculator
Calculate the volume and surface area of a capsule (a cylinder with hemispherical ends).
Σ The Formula
V = πr²(h + 4r/3)
Real World Examples
Medicine Pill
r=2mm, h=5mm → V=96.34 mm³
Storage Tank
r=1m, h=4m → V=16.76 m³
# About This Calculator
A Capsule (or spherocylinder) is a three-dimensional geometric shape composed of a cylinder with hemispherical ends. It is the shape of many common items, including antibiotic pills, large propane storage tanks, and even the hulls of some submarines.
Calculating the volume of a capsule involves adding the volume of the central cylinder to the volume of the two hemispheres (which together form a complete sphere of the same radius).
How To Use
- Enter the **Radius** of the capsule (the radius of both the cylinder and the ends).
- Enter the **Height** of the cylinder section only (excluding the rounded ends).
- Click **Analyze Capsule** to get volume and surface area results.
Frequently Asked Questions
Does 'height' include the ends?+
In this calculator, 'Height' refers specifically to the side of the cylinder section. The total length of the capsule would be Height + 2 × Radius.
Is surface area for the whole shape?+
Yes, the calculation includes both the cylindrical wall and the entire surface of the two spherical caps.
Is Capsule Calculator free to use?+
