About Megahenries
The megahenry (MH) equals 10⁶ H, well beyond any practical wound inductor but arising in theoretical analysis of very large electromagnetic structures. Extremely long overhead transmission line sections have distributed inductance totalling megahenries; electromagnetic pulse (EMP) source models and magnetosphere inductance estimates use MH in theoretical contexts. 1 MH = 10³ kH = 10⁶ 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.
