Planck temperature

The Planck temperature, named after German physicist Max Planck, is the natural unit of temperature, denoted by T_P.

$T_P = \frac{m_P c^2}{k} = \sqrt{\frac{\hbar c^5}{G k^2}} =$ 1.41679 × 10³² K

where:

m_p is the Planck length

c is the speed of light in a vacuum

$\hbar$ is Dirac's constant

k is the Boltzmann constant
