About Abhenries
The abhenry (abH) is the inductance unit of the CGS-EMU system, equal to 1 abΩ × 1 s = 10⁻⁹ Ω × 1 s = 10⁻⁹ H, exactly equal to 1 nH in SI. It appears in nineteenth- and early-twentieth-century electromagnetic engineering texts alongside abohms and abamperes; the abhenry was the standard inductance unit in EMU telegraphy and early radio literature. 1 abH = 10⁻⁹ H = 1 nH.
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.
