# Black Hole Schwarzschild Radius Calculator

A region in space which does not allow anything to pass out with such a gravity pull is called as the black hole or the event horizon. The radius of the boundary of such an event horizon (hole) is called as the schwarzschild or the gravitational radius. Which can be calculated based on the gravitational constant, light speed and body mass.

#### Formula:

r_{s} = 2GM / c^{2}
**Where,**
r_{s} = Black Hole Schwarzschild Radius
G = Constant of Gravitation
M = Mass of Body
c = Speed of Light
