Formula For The Schwarzschild Radius
The Schwarzschild radius is proportional to the mass with a proportionality constant involving the gravitational constant and the speed of light:
where:
- is the Schwarzschild radius;
- is the gravitational constant;
- is the mass of the object;
- is the speed of light in vacuum.
The proportionality constant, 2G/c2, is approximately 1.48×10−27 m/kg, or 2.95 km/solar mass.
An object of any density can be large enough to fall within its own Schwarzschild radius,
where:
- is the volume of the object;
- is its density.

“But suppose, asks the student of the professor, we follow all your structural rules for writing, what about that “something else” that brings the book alive? What is the formula for that? The formula for that is not included in the curriculum.”
—Fannie Hurst (1889–1968)
“Ideals possess the strange quality that if they were completely realized they would turn into nonsense. One could easily follow a commandment such as “Thou shalt not kill” to the point of dying of starvation; and I might establish the formula that for the proper functioning of the mesh of our ideals, as in the case of a strainer, the holes are just as important as the mesh.”
—Robert Musil (1880–1942)
