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.
About Femtofarads per metre
The femtofarad per metre (fF/m) equals 10⁻¹⁵ F/m, the smallest practical permittivity scale. Permittivity of near-perfect vacuum regions at sub-pF/m levels, noise-floor permittivity in cryogenic microwave resonators, and modelled permittivity of hypothetical near-zero-index metamaterial layers all span the fF/m range. 1 fF/m = 10⁻¹⁵ F/m = 10⁻³ pF/m.
