Conversion Formula
kF/m = pF/cm × 1.000000000e-13
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 Kilofarads per metre
The kilofarad per metre (kF/m) equals 10³ F/m, appearing in theoretical models of heavily screened plasmas and ionic liquids at very low frequencies. The London penetration depth model for superconductors treated as a dielectric gives effective permittivities of 10³-10⁶ F/m in the microwave range; ionic double-layer capacitance per unit length of nanowire electrodes scales to kF/m. 1 kF/m = 10³ F/m.
