About Gigahenries

The gigahenry (GH) equals 10⁹ H. No engineered discrete inductor approaches this value; gigahenry figures arise in geophysical induction modelling of the Earth's crust and mantle, magnetohydrodynamic models of stellar interiors, and theoretical scaling studies of superconducting magnetic energy storage (SMES) systems at utility scale. 1 GH = 10³ MH = 10⁹ H.

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.
