Planck pressure

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

$p_P = \frac{F_P}{l_P^2} = \frac{c^7}{\hbar G^2} \approx$ 4.63309 × 10¹¹³ Pa

where

F_P is the Planck force

c is the speed of light in a vacuum

$\hbar$ is the reduced Planck's constant

G is the gravitational constant

l_P is the Planck length
