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 Statfarads per centimetre
The statfarad per centimetre (statF/cm) is the permittivity unit of the CGS-Gaussian system, exactly equal to 4πε₀ = 10⁷/c² F/m ≈ 1.11265 × 10⁻¹⁰ F/m. In Gaussian units Gauss's law is ∇·E = 4πρ so the permittivity of free space is 1/(4π) statF/cm; the statF/cm is used in older plasma physics and quantum electrodynamics texts. 1 statF/cm ≈ 1.11265 × 10⁻¹⁰ F/m.
