The relationship between the mass, <math>~M</math>, and radius, <math>~R</math>, of a black hole is,

<math>~\frac{GM}{c^2 R}</math>

<math>~=</math>

<math>~1 \, .</math>

The mean density of matter inside a black hole of mass <math>~M</math> is, therefore,

<math>~\bar\rho</math>

<math>~=</math>

<math>~ \frac{3M}{4\pi R^3} </math>

 

<math>~=</math>

<math>~ \frac{3M}{4\pi} \biggl[ \frac{GM}{c^2}\biggr]^{-3} </math>

 

<math>~=</math>

<math>~ \frac{3c^6}{4\pi G^3 M^2} \, . </math>
