Instructions to Use

  • Enter the mass of the black hole in kg.
  • If mass is “2 x $10^{30}$ kg”, then just type “2e+30”.
  • If your result is “1.4E+54 J/K” then it is equal to “1.4 x $10^{54}$ J/K”

 

About Equation

Here,

  • M is the mass of the black hole
  • G is the Gravitational constant 
  • h is the plank’s constant
  • c is the speed of light
  • k is Boltzmann’s constant
