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 Attohenries
The attohenry (aH) equals 10⁻¹⁸ H, the scale for parasitic inductances in on-chip metal interconnects and quantum-device bondwires. Metal traces in sub-10 nm CMOS processes have via-to-via inductances in the attohenry range; superconducting qubit junctions are modelled with loop inductances of tens to hundreds of attohenries; microwave integrated circuit (MMIC) vias at 100 GHz are characterised in aH. 1 aH = 10⁻³ fH = 10⁻¹⁸ H.
