Planck voltage

The Planck voltage is the unit of voltage, denoted by V_P, in the system of natural units known as Planck units.

$V_{P}={\frac {E_{P}}{q_{P}}}={\sqrt {\frac {c^{4}}{G4\pi \epsilon _{0}}}}\approx$ 1.04295 × 10²⁷ V

where

$E_{P}$ is the Planck energy

$q_{P}$ is the Planck charge

$c$ is the speed of light in a vacuum

$G$ is the gravitational constant
