WEBJul 18, 2020 · From the perspective of particle physics, you are correct, the Planck length and Planck mass are essentially equivalent concepts: the Planck mass describes a (very high) energy scale ($\sim 10^{19}$ GeV) at which new physics must emerge, just as the Planck length entails a (very short) length scale beyond which we need a new description.

Planck mass - Simple English Wikipedia, the free encyclopedia
https://simple.wikipedia.org/wiki/Planck_mass
WEBThe Planck mass is a small unit of mass used in physics. It is derived using an equation involving Planck's constant, the speed of light in a vacuum, and the gravitational constant. It is approximately 21.76 µg, which is a few times less than the mass of a human eyelash.

WEBcosmology and string theory. …a Planck volume is a Planck mass ( hc / G) 1/2, roughly 10 −5 gram. An object of such mass would be a quantum black hole, with an event horizon close to both its own Compton length (distance over which a particle is quantum mechanically “fuzzy”) and the size of the cosmic horizon at….

WEBDec 30, 2020 · Planck units. Page ID. Many people are familiar with the idea that in special relativity, we can set the speed of light equal to one. This is simply a choice of units -- it means that if we measure time in seconds, we should measure distance in light seconds. (After all, the speed of light is one light second per second.)
