[Planck mass is a] natural unit of mass that can be obtained by combining the fundamental natural constants that govern spacetime, the strength of gravity and the quantum world : the gravitational constant, Planck's constant and the speed of light. Compared with the masses we’re used to in everyday life, the Planck mass is rather small, a mere 2 hundredths of a thousandth of a gram. 2, record 1, English, - Planck%20mass

The Planck units are characteristics of the properties of the Universe during its first moments. The standard Big Bang model can account for the evolution of the Universe back to around the Planck time, when the Universe was at the Planck temperature and the mean energy of photons was close to the Planck energy. 2, record 2, English, - Planck%20unit
