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

$p_\text{P} = \frac{F_\text{P}}{l_\text{P}^2} = \frac{c^7}{\hbar G^2} \approx$ 4.63309 × 10¹¹³ Pa

where

$F_\text{P}$ 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

$l_\text{P}$ is the Planck length
