Planck mass

[′pläŋk ‚mas]
(physics)
The mass √(hc /2π G), where h is Planck's constant, c is the speed of light, and G is the gravitational constant; equivalently, the mass of a particle whose reduced Compton wavelength equals the Planck length; it is equal to 21.764 micrograms or 1.2209 × 1019GeV/ c 2.

Various calculations based on theory dictate that the Higgs mass should be comparable to a figure called the Planck mass, which is about 17 orders of magnitude higher than the boson's measured heft (SN Online: 10/22/13).
As a result we find that the number of information N can be expressed as the square of the ratio of two fundamental masses, namely, the Planck mass and the mass of the graviton or the square of the total number of gravitons in the universe over the Planck mass.

The constants contained within his formulation, those of Planck and Boltzmann (h and k), became fundamental to all of physics, leading to the development of Planck length, Planck mass, Planck time, and Planck temperature [3, p.
