Common Permittivity Conversions

• ε₀ (vacuum) = 8.8541878128 pF/m (exact reference value)
• 1 F/m = 10¹² pF/m = 10⁹ nF/m = 10⁶ µF/m (SI chain)
• 1 pF/cm = 100 pF/m = 10^-10 F/m (RF transmission line scale)
• 1 statF/cm = 4πε₀ ≈ 1.11265 × 10^-10 F/m (CGS-Gaussian, exact: 10⁷/c² F/m)
• 1 abF/cm = 10¹¹ F/m (CGS-EMU, exact: 10⁹ F / 0.01 m)
• FR-4 PCB substrate: ε ≈ 37 pF/m (ε_r ≈ 4.2 × ε₀)
