Summary
Enter a capsule's radius and cylindrical body height to instantly calculate its volume and surface area.
How it works
- Enter the radius of the capsule (the radius of both the cylinder and the hemispheres).
- Enter the height of the cylindrical body only (not including the hemispherical ends).
- Select your preferred unit (mm, cm, m, in, ft).
- Volume and surface area results appear instantly.
- Click any result card to copy the value to your clipboard.
Use cases
- Estimate volume of pharmaceutical capsules and drug delivery containers.
- Calculate volume of propane or fuel tanks with domed ends.
- Determine capacity of pressurized vessels used in engineering.
- Compute volume of swimming pool lanes or capsule-shaped pools.
- Verify geometry homework answers for capsule or stadium-of-revolution problems.
- Model volume of biological cells with rounded cylindrical shapes.
- Calculate material needed for capsule-shaped packaging or containers.
