Convert Microhenries to Millihenries
Convert Microhenries (µH) to Millihenries (mH) instantly and accurately.
Conversion Formula
mH = µH × 0.001
About Microhenries
The microhenry (µH) equals 10⁻⁶ H, the standard unit for power-electronics inductors, EMI filter chokes, and AM radio coils. DC-DC converter inductors in smartphones are 1-100 µH; ferrite-core EMI common-mode chokes are 10-10 000 µH; AM broadcast loop antennas are 200-500 µH; automotive ignition coil secondary inductances are a few µH. 1 µH = 10⁻³ mH = 10⁻⁶ 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.
