Conversion Formula
kH = aH × 1.000000000e-21
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.
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.
