Convert Terahenries to Nanohenries
Convert Terahenries (TH) to Nanohenries (nH) instantly and accurately.
Conversion Formula
nH = TH × 1.000000000e+21
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 Nanohenries
The nanohenry (nH) equals 10⁻⁹ H, the everyday unit for RF inductors, PCB trace inductance, and package parasitics. A 10 mm PCB microstrip trace is about 10 nH; surface-mount RF chokes range from 1 to 1 000 nH; bond-wire lead inductances are 1-20 nH; resonant LC tank circuits for Bluetooth and Wi-Fi use inductors of 1-100 nH. 1 nH = 10⁻³ µH = 10⁻⁹ H.
