Convert Femtohenries to Terahenries
Convert Femtohenries (fH) to Terahenries (TH) instantly and accurately.
Conversion Formula
TH = fH × 1.000000000e-27
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.
About Terahenries
The terahenry (TH) equals 10¹² H. No physical inductor or coil approaches 1 TH; the value is used in dimensional scaling of cosmic electromagnetic phenomena (e.g., inductance of galactic current sheets) and in theoretical discussions of extreme-value electromagnetic parameters. The stathenry is ≈ 0.899 TH, placing stathenries and terahenries in the same order of magnitude. 1 TH = 10³ GH = 10¹² H.
