About Farads per metre

The farad per metre (F/m) is the SI coherent unit of permittivity. It is an extremely large unit in practice - the vacuum permittivity ε₀ is only 8.854 × 10⁻¹² F/m. Permittivities in F/m arise in models of quasi-metallic electrolytes and ultralow-frequency behaviour of plasma where ionic screening raises the effective dielectric constant enormously. 1 F/m = 10³ mF/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.
