About Statcoulombs per centimetre
The statcoulomb per centimetre (statC/cm) is the linear charge density unit of the CGS-Gaussian system, equal to 10/c C/m where c = 299 792 458 m/s, giving exactly 10/299 792 458 C/m ≈ 3.336 × 10⁻⁸ C/m. It falls between nC/m and µC/m in the SI scale; the electric field of a line charge is written E = 2λ/r in Gaussian units without a 4πε₀ factor. 1 statC/cm ≈ 33.356 nC/m.
About Coulombs per inch
The coulomb per inch (C/in) equals exactly 1/0.0254 C/m ≈ 39.370 C/m, used in insulation specifications and dielectric withstand testing at the component level. Dielectric tape and insulating sleeve charge retention is sometimes expressed in C/in in US industry datasheets; PCB creepage and clearance charge density specifications for high-voltage designs appear in C/in. 1 C/in = 1/0.0254 C/m ≈ 39.370 C/m.
