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 Femtocoulombs per metre
The femtocoulomb per metre (fC/m) equals 10⁻¹⁵ C/m, arising in scanning probe measurements of charged surface features and in single-molecule electrostatic force microscopy. A single elementary charge (1.6 × 10⁻¹⁹ C) localised on a 1 µm polymer segment gives about 0.16 fC/m; EFM tip-sample interaction models use fC/m-scale induced charge distributions. 1 fC/m = 10⁻¹⁵ C/m = 10⁻³ pC/m.
