Planck Temperature

        

Planck Temperature Formula
\( T_p \;=\; \dfrac{ E_p }{ k } \)     (Planck Temperature) \( E_p \;=\; T_p \cdot k\) \( k \;=\; \dfrac{ E_p }{T_p } \)
Symbol	English	Metric
\( T_p \) = Planck temperature (See Physics Constants)	\(F\)	\(K\)
\( E_p \) = Planck energy	\(lbf-ft\)	\(J\)
\( k \) = Boltzmann constant	\(lbm-ft^2\;/\;sec^2\)	\(kJ\;/\;molecule-K\)

Planck temperature, abbreviated as \(tT_p\), is a fundamental unit in the system of Planck units.  This temperature is the highest theoretically possible temperature in the universe according to current physical theories.  It is derived from fundamental constants such as the speed of light, the gravitational constant, and the reduced Planck constant. 

At temperatures close to the Planck temperature, the effects of quantum gravity become significant, and conventional physical theories such as general relativity and quantum field theory are expected to break down.  Thus, the Planck temperature serves as a fundamental limit beyond which our current understanding of physics cannot describe the universe accurately.
