Planck Charge

q_P = \sqrt{4 \pi\epsilon_0 \hbar c} = \sqrt{2 c h \epsilon_0} = rac{e}{\sqrt{\alpha}}

where :

:

c \

is the Speed Of Light in a Vacuum ,
:

h \

\hbar \equiv rac{h}{2 \pi} \

is the ''reduced'' Planck's constant or Dirac's Constant ,
:

\epsilon_0 \

e \

\alpha \

= (137.03599911)⁻¹ is the Fine Structure Constant .

Its value as expressed in SI units is

:

q_P \

= 1.8755459 × 10 ⁻¹⁸ C .
