"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."^^ . .
