About Abfarads per centimetre
The abfarad per centimetre (abF/cm) is the permittivity unit of the CGS-EMU system, equal to 10⁹ F / 0.01 m = 10¹¹ F/m. The abfarad (= 10⁹ F exactly) was the CGS-EMU base capacitance unit; in EMU notation electromagnetic wave propagation uses abF/cm. 1 abF/cm = 10¹¹ F/m = 10⁹ GF/m.
About Picofarads per centimetre
The picofarad per centimetre (pF/cm) equals 10⁻¹⁰ F/m = 100 pF/m, used for transmission-line capacitance per unit length in RF engineering. A standard 50 Ω air-dielectric coaxial line has capacitance per unit length ≈67 pF/m ≈0.67 pF/cm; PTFE coax gives ≈0.9 pF/cm. RF substrate characterisation often quotes pF/cm. 1 pF/cm = 10⁻¹⁰ F/m.
