    Here’s an easy way to calculate the Schwarzschild radius since black holes are almost always given in solar masses.

    The Schwarzschild radius of the sun (1 solar mass) is about 3km. The radius is directly proportional to mass so the radius of a black hole of 8 solar masses is simply 3x8 = 24 km.
