About Stathenries
The stathenry (statH) is the inductance unit of the CGS-Gaussian system, equal to 1 statΩ × 1 s = c² × 10⁻⁵ H where c = 299 792 458 m/s, giving exactly (299 792 458)² / 10⁵ H ≈ 8.988 × 10¹¹ H. It is the reciprocal of the statfarad in terms of LC time constants and appears in Gaussian-system circuit analysis; the enormous SI value reflects the Gaussian unit's origin in electrostatics rather than practical circuits. 1 statH ≈ 899 GH.
About Femtohenries
The femtohenry (fH) equals 10⁻¹⁵ H, the scale for PCB via inductances, short bondwires, and on-chip spiral inductor parasitics in millimetre-wave design. A 0.5 mm gold bondwire has about 0.5-1 fH inductance at mm-wave frequencies; differential pair stubs in 100 GHz SerDes are modelled in femtohenries; Josephson junction loop inductances in superconducting circuits are a few hundred fH. 1 fH = 10⁻³ pH = 10⁻¹⁵ H.
