The Weight (Mass) of a Capsule calculator computes mass or weight of a capsule, also known as a spherocylinder. Capsule  Spherocylinder
INSTRUCTIONS: Choose units (e.g. meters or feet) and enter the following:
Capsule Mass (M): The calculator computes the mass in kilograms. However this can be automatically converted in the many other mass or weight units (e.g. pounds, metric tons) via the pulldown menu.
Note: the formula assumes hemispheres (half spheres) on either side of the capsule cylinder.
Geometrically, a capsule is a cylinder of any length (l) with two hemispheres on either end where the radius (r) of the cylinder is equal to the radius of the hemispheres. See diagram. This formula computes the volume of the geometric shape based on the input parameters. With the computed volume, this formula then executes the simple equation below to compute the approximate mass of the object.
Spherocylinders are found in many applications. The most common are in capsule containers such small pills and large containers such as liquid or gas transport containers.

Mean Density is the average amount of mass within a volume for a substance. Note, volume of a material is often highly subject to the temperatures, since materials expand as they warm. For that reason, mean densities of substances are often cited with a set of nominal conditions such as temperature and barometric pressure.
The formula for mean density is:
μD = V / m
where:
Mean density is also often indicated as the Greek symbol rho (ρ).
Density is a function of mass. However, converting from mass to weight is trivial under the right conditions. Fortunately those conditions are generally true anywhere on the surface of the Earth, so the conversions built into the vCalc engine can be assumed to be fairly accurate unless you require weight at very high altitudes or in space.

Mean density is scientifically volume divided by mass. There are various unit for density adopted by cultures and industries. Common units for density included the following:
vCalc provides for automatic conversions between density units via the pulldown menus.
