Convert Millihenries to Megahenries
Convert Millihenries (mH) to Megahenries (MH) instantly and accurately.
Conversion Formula
MH = mH × 1.000000000e-9
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 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.
