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.

It is customary in gravitation to work with the reduced Planck mass, [m.
Suppose a dense ring of radius r = m is quantised by subdivision into a circular arrangement of N particles, each of roughly the reduced Planck mass, such that N = m/[m.
