The Ultimate Planck charge - American History Information Guide and Reference

In physics, the Planck charge is the natural unit of electric charge, denoted by $q p$ . It is defined as

$q_p = (2ch\epsilon_0)^\frac{1}{2}$

where :

ε 0

Its value as expressed in SI units is

q p

= 1.875 × 10⁻¹⁸ C.

It is about 11.7 times the charge on an electron, ignoring the sign.
