The Density of a Sphere calculator computes the density a sphere (ρ) based on the radius (r) of the sphere and the mass (M).

INSTRUCTIONS:  Choose units and enter the following:

• (r) Radius of Sphere
• (M) Mass of Sphere

Sphere Density (ρ) : The Density of the Sphere (ρ) is returned in kilograms per cubic meter.  However, this can be automatically converted to other density units via the pull-down menu.  The calculator also returns the volume of the sphere (V) used in computing the density.

The Math / Science

The formula for density is:

• σ= M/V

The equation for the volume of a sphere is as follows:

           V = 4/3•π•r³

The two formulas are combined in this calculator:

• σ= M/(4/3•π•r³)
