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.

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

where

$c$ is the speed of light in a vacuum

$\hbar$ is the reduced Planck's constant

$G$ is the gravitational constant
