Capsule surface area calculator: calculate capsule, pill shape, or spherocylinder surface area from radius or diameter and cylindrical height or total length, with reverse solving for a missing size.
This calculator finds the surface area of a capsule from the radius or diameter and the cylindrical height or the total length. It works for capsule, pill, and spherocylinder shapes.
The calculator can also work in reverse when the surface area is already known and you want to solve for a missing radius, diameter, height, or length. This is useful in geometry, 3D modelling, and technical calculations.
