Applying Gauss's law using a cylindrical pillbox extending above and below a charged infinite plane in cgs, the electric field satisfies
(1)

where is the unit normal and is the surface charge density. By symmetry, , so
(2)

and solving for E gives
(3)

Similarly, in MKS
(4)

where is the permittivity of free space, by symmetry,,
(5)

so
