Planck angular frequency

The Planck angular frequency is the unit of angular frequency, denoted by ω_P, in the system of natural units known as Planck units.

$\omega _{\text{P}}={\frac {1}{t_{\text{P}}}}={\sqrt {\frac {c^{5}}{\hbar G}}}\approx$ 1.85487 × 10⁴³ s⁻¹

where

$t_{\text{P}}$ is the Planck time,

$c$ is the speed of light in a vacuum,

$\hbar$ is the reduced Planck's constant,

$G$ is the gravitational constant.
