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 Henries
The henry (H) is the SI derived unit of electrical inductance, equal to 1 volt-second per ampere (1 V·s/A = 1 Ω·s = 1 kg·m²·A⁻²·s⁻²), named after Joseph Henry (1797-1878). Mains-frequency (50/60 Hz) power transformers have primary inductances of 1-100 H; loudspeaker crossover woofer inductors are 1-5 mH; large power-line reactors are 0.1-10 H. 1 H = 10³ mH = 10⁶ µH.
