The formula

S = entropy (a thermodynamic quantity representing the unavailability of a

system’s thermal energy for conversion into mechanical work)

h = Planck constant (the energy of a quantum of electromagnetic radiation

divided by its frequency)

G = Newton’s constant (universal gravitational constant)

A = area of event horizon (a boundary in spacetime beyond which events

cannot affect an outside observer)

c = speed of light

k = Boltzmann’s constant (relates the average kinetic energy of particles

in a gas with the temperature of the gas)
