Conversion Formula
nF/m = pF/cm × 0.1
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.
About Nanofarads per metre
The nanofarad per metre (nF/m) equals 10⁻⁹ F/m, the scale for high-permittivity dielectrics. Barium titanate (BaTiO₃) has peak relative permittivity εᵣ ~ 10 000 at the Curie temperature, giving ε ≈ 88.5 nF/m; aluminium oxide (Al₂O₃) anodic films at εᵣ ~ 10 give ≈88.5 nF/m for thick-film applications. 1 nF/m = 10⁻⁹ F/m = 10³ pF/m.
