Conversion Formula
fH = pH × 1000
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.
About Femtohenries
The femtohenry (fH) equals 10⁻¹⁵ H, the scale for PCB via inductances, short bondwires, and on-chip spiral inductor parasitics in millimetre-wave design. A 0.5 mm gold bondwire has about 0.5-1 fH inductance at mm-wave frequencies; differential pair stubs in 100 GHz SerDes are modelled in femtohenries; Josephson junction loop inductances in superconducting circuits are a few hundred fH. 1 fH = 10⁻³ pH = 10⁻¹⁵ H.
