Questions & answers

What does Capsule Volume Calculator calculate?

Calculate a cylinder with two hemispherical ends.

Which units should I enter?

Radius uses cm. Straight cylinder length uses cm. Convert values to these units before calculating.

Which formula does it use?

Volume = πr²l + 4πr³/3.

What does the included example show?

Radius: 3 cm; Straight cylinder length: 10 cm. Result: Volume · cm³ = 395.84067; Total length · cm = 16; Surface · cm² = 301.59289.

Can I compare different settings?

Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.

Can I export the calculation?

Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
