Conversion Formula

pH = mH × 1000000000

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.

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.
