Convert Millihenries to Kilohenries
Convert Millihenries (mH) to Kilohenries (kH) instantly and accurately.
Conversion Formula
kH = mH × 1.000000000e-6
About Millihenries
The millihenry (mH) equals 10⁻³ H, the scale for audio-frequency transformers, relay coils, and resonant filter inductors. Telephone voice-frequency transformers use 10-200 mH; relays and solenoids have coil inductances of 1-100 mH; tunable AM IF transformers operate at 200-500 mH; loudspeaker crossover inductors (2-8 kHz) are typically 0.5-5 mH. 1 mH = 10⁻³ H = 10³ µH.
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.
