Schwarzschild Radius Calculator
The Schwarzschild radius is the size of a massive object when the escape velocity—the speed required to escape its gravitational pull—is greater than or equal to the speed of light. Simply put, it is used to calculate the size (radius) of a massive object when it becomes a black hole.
5.97420×10^24 is the value generally accepted as the mass of the Earth; according to the Schwarzschild radius, if compressed to a diameter of approximately 1.8 cm, it would become a black hole.
1.98892×10^30 is the value generally accepted as the mass of the Sun; according to the Schwarzschild radius, compressing it to a diameter of approximately 6 km would result in a black hole.

The Schwarzschild radius, r = 2GM/C², is derived as follows:
G = gravitational constant
M = mass of the object
C = speed of light
