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 metre
The picofarad per metre (pF/m) equals 10⁻¹² F/m, the most widely used permittivity scale. The vacuum permittivity ε₀ ≈ 8.854 pF/m; air at STP is ≈8.859 pF/m; PTFE PCB substrate is ≈19 pF/m; FR-4 laminate is ≈37 pF/m. Dielectric specifications in IPC-4101 and IEC 60250 list pF/m values. 1 pF/m = 10⁻¹² F/m.
