Planck pressure

Planck pressure

The Planck pressure is the unit of pressure, denoted by pP, 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
