Convert Gigahenries to Millihenries
Convert Gigahenries (GH) to Millihenries (mH) instantly and accurately.
Conversion Formula
mH = GH × 1000000000000
About Gigahenries
The gigahenry (GH) equals 10⁹ H. No engineered discrete inductor approaches this value; gigahenry figures arise in geophysical induction modelling of the Earth's crust and mantle, magnetohydrodynamic models of stellar interiors, and theoretical scaling studies of superconducting magnetic energy storage (SMES) systems at utility scale. 1 GH = 10³ MH = 10⁹ H.
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.
