Convert Terahenries to Attohenries
Convert Terahenries (TH) to Attohenries (aH) instantly and accurately.
Conversion Formula
aH = TH × 1.000000000e+30
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.
About Attohenries
The attohenry (aH) equals 10⁻¹⁸ H, the scale for parasitic inductances in on-chip metal interconnects and quantum-device bondwires. Metal traces in sub-10 nm CMOS processes have via-to-via inductances in the attohenry range; superconducting qubit junctions are modelled with loop inductances of tens to hundreds of attohenries; microwave integrated circuit (MMIC) vias at 100 GHz are characterised in aH. 1 aH = 10⁻³ fH = 10⁻¹⁸ H.
