Conversion Formula

nH = mH × 1000000

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 Nanohenries

The nanohenry (nH) equals 10⁻⁹ H, the everyday unit for RF inductors, PCB trace inductance, and package parasitics. A 10 mm PCB microstrip trace is about 10 nH; surface-mount RF chokes range from 1 to 1 000 nH; bond-wire lead inductances are 1-20 nH; resonant LC tank circuits for Bluetooth and Wi-Fi use inductors of 1-100 nH. 1 nH = 10⁻³ µH = 10⁻⁹ H.
