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.
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.
