Convert Picofarads per centimetre to Gigafarads per metre
Convert Picofarads per centimetre (pF/cm) to Gigafarads per metre (GF/m) instantly and accurately.
Conversion Formula
GF/m = pF/cm × 1.000000000e-19
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 Gigafarads per metre
The gigafarad per metre (GF/m) equals 10⁹ F/m. Effective permittivity of a dense metallic plasma (electron density ~10²⁶ m⁻³) at frequencies well below the plasma frequency can reach GF/m; abfarad-scale geometric capacitances in nanoelectronics expressed per unit electrode length approach GF/m. 1 GF/m = 10⁹ F/m = 10³ MF/m.
