About Abcoulombs per centimetre

The abcoulomb per centimetre (abC/cm) is the linear charge density unit of the CGS-EMU system, equal to 1 abC / 1 cm = 10 C / 0.01 m = 1 000 C/m, exactly equal to 1 kC/m in SI. It appears in nineteenth-century electromagnetic engineering texts on telegraphy cables and in EMU derivations of inductance and capacitance per unit length. 1 abC/cm = 1 000 C/m = 1 kC/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.
