Convert Gigahenries to Femtohenries
Convert Gigahenries (GH) to Femtohenries (fH) instantly and accurately.
Conversion Formula
fH = GH × 1.000000000e+24
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.
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.
