Description

In physics, the Planck mass, denoted by mP, is the unit of mass in the system of natural units known as Planck units. It is defined so that 1.2209×10GeV/c0=2.17651(13)×10kg, (or 21.7651μg), where c0 is the speed of light in a vacuum, G is the gravitational constant, and is the reduced Planck constant. Particle physicists and cosmologists often use the reduced Planck mass, which is 4.341×10kg=2.435×10GeV/c. The added factor of 1/8π simplifies a number of equations in general relativity. Quantum effects are typified by the magnitude of Planck's constant.
