Convert Megahenries to Picohenries
Convert Megahenries (MH) to Picohenries (pH) instantly and accurately.
Conversion Formula
pH = MH × 1.000000000e+18
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.
About Picohenries
The picohenry (pH) equals 10⁻¹² H, the practical unit for short PCB traces, decoupling capacitor equivalent series inductance (ESL), and bond-wire inductance in RF packages. A 1 mm PCB trace (50 Ω microstrip) has about 1 nH/mm; SMD bypass capacitors have ESL of 0.1-2 nH; gold bondwires are 1-5 pH/mm. IC package lead inductances are typically 1-10 nH = 1 000-10 000 pH. 1 pH = 10⁻³ nH = 10⁻¹² H.
