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 Megahenries
The megahenry (MH) equals 10⁶ H, well beyond any practical wound inductor but arising in theoretical analysis of very large electromagnetic structures. Extremely long overhead transmission line sections have distributed inductance totalling megahenries; electromagnetic pulse (EMP) source models and magnetosphere inductance estimates use MH in theoretical contexts. 1 MH = 10³ kH = 10⁶ H.
