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.
About Gigahenries
The gigahenry (GH) equals 10⁹ H. No engineered discrete inductor approaches this value; gigahenry figures arise in geophysical induction modelling of the Earth's crust and mantle, magnetohydrodynamic models of stellar interiors, and theoretical scaling studies of superconducting magnetic energy storage (SMES) systems at utility scale. 1 GH = 10³ MH = 10⁹ H.
