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


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
