Conversion Formula
mH = abH × 1.000000000e-6
About Abhenries
The abhenry (abH) is the inductance unit of the CGS-EMU system, equal to 1 abΩ × 1 s = 10⁻⁹ Ω × 1 s = 10⁻⁹ H, exactly equal to 1 nH in SI. It appears in nineteenth- and early-twentieth-century electromagnetic engineering texts alongside abohms and abamperes; the abhenry was the standard inductance unit in EMU telegraphy and early radio literature. 1 abH = 10⁻⁹ H = 1 nH.
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.
