Type
Description

In physics, the unit of energy in the system of natural units known as Planck units is called the Planck energy, denoted by $$E_P$$. $$E_P$$ is a derived, as opposed to basic, Planck unit. An equivalent definition is:$$E_P = \hbar / T_P$$ where $$T_P$$ is the Planck time. Also: $$E_P = m_P c^2$$ where $$m_P$$ is the Planck mass.

$$E_\rho = \sqrt{\frac{ \hbar c^5}{G}} \approx 1.936 \times 10^9 J \approx 1.22 \times 10^{28} eV \approx 0.5433 MWh$$, where $$c$$ is the speed of light in a vacuum, $$\hbar$$ is the reduced Planck's constant, and $$G$$ is the gravitational constant.
