# Planck Energy

on . Posted in Relativity

Planck energy, abbreviated as $$E_p$$, is a fundamental unit in the system of Planck units.  It is a useful unit in theoretical physics.

• $$\large{ E_p = 1.956 \;x\;10^{9}\;J }$$

## Planck Energy Formula

$$\large{ E_p = m_p\;c^2 }$$
Symbol English Metric
$$\large{ E_p }$$ = Planck energy $$\large{lbf-ft}$$  $$\large{J}$$
$$\large{ m_p }$$ = Planck mass $$\large{lbm}$$ $$\large{kg}$$
$$\large{ c }$$ = speed of light in vacuum  $$\large{\frac{ft}{sec}}$$  $$\large{\frac{m}{s}}$$
