kH = fH × 1.000000000e-18
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 Kilohenries
The kilohenry (kH) equals 10³ H, encountered in the inductance of very-low-frequency (VLF) antenna loading coils and large power-system shunt reactors. Submarine communication transmitters at 10-30 kHz use loading coils of 100-2 000 H = 0.1-2 kH; high-voltage shunt reactors in 400 kV grid substations have inductances of around 100-1 000 H = 0.1-1 kH. 1 kH = 10³ H = 10⁻³ MH.
