Capsule Calculator
Result
Capsule Calculator Calculate the volume and surface area of a capsule (a cylinder with a hemispherical cap on each end — the classic pill shape). Enter the radius and the cylinder height, and this calculator returns the volume, surface area, and total hei — free online calculator.
Formula
- Capsule surface area and volume calculator. This page states the geometric relationship used by the calculator and provides a worked example.
- The main inputs are Radius, Cylinder Height. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Capsule
- Radius: 3 cm
- Cylinder Height: 8 cm
For r=1 and cylinder height h=4, surface area=12π and volume=16π/3.

Frequently asked questions
What does the Capsule calculate?
Here h is the cylindrical section only; the two hemispherical ends together form one sphere.
Which values should I enter?
Enter Radius, Cylinder Height using the units and format shown beside each field.
What formula does this calculator use?
The calculator uses the following relationship: V=πr²(h+4r/3); A=2πr(h+2r); H=h+2r.
Why might my result differ from another source?
Results can differ when another source uses different units, rounding rules, conventions or assumptions. Compare the inputs and definitions before comparing results.
Does the result update automatically?
Yes. Changing an input updates the result using the same calculation engine shown on this page.
