Description	In physics, the Planck mass, denoted by \(m_P\), is the unit of mass in the system of natural units known as Planck units. It is defined so that \(\approx 1.2209 \times 10 GeV/c_0 = 2.17651(13) \times 10 kg\), (or \(21.7651 \mu g\)), where \(c_0\) is the speed of light in a vacuum, \(G\) is the gravitational constant, and \(\hbar\) is the reduced Planck constant. Particle physicists and cosmologists often use the reduced Planck mass, which is \(\approx 4.341 \times 10 kg = 2.435 \times 10 GeV/c\). The added factor of \(1/{\sqrt{8\pi}}\) simplifies a number of equations in general relativity. Quantum effects are typified by the magnitude of Planck's constant.
