Planck energy

The Planck energy is the natural unit of energy, denoted by E_P.

$E_p = c^2 \sqrt{c \hbar G} \approx$ 1.956 × 10⁹ J or 10¹⁹ GeV

where:

$c$ is the speed of light in a vacuum

$\hbar$ is Dirac's constant

$G$ is the gravitational constant

The Planck energy is also the amount of energy contained in the Planck mass of about a small flea, not counting the kinetic and potential energies.

Planck energy is approx= 10 million million million GeV (1 with nineteen zeros following it). A more accurate measurement is provided above.
