Convert Gigaohms to Nanoohms
Convert Gigaohms (GΩ) to Nanoohms (nΩ) instantly and accurately.
Conversion Formula
nΩ = GΩ × 1.000000000e+18
About Gigaohms
The gigaohm (GΩ) equals 10⁹ Ω, the regime of PTFE and glass insulation, MOSFET gate oxide, and specialised electrometer inputs. High-quality PCB insulation resistance between adjacent tracks exceeds 10 GΩ; the reverse-leakage resistance of a silicon junction at room temperature is in the gigaohm range; the guarded input of a Keithley 6517B electrometer is rated at 200 TΩ, but JFET-input op-amps commonly show input resistance of a few GΩ. 1 GΩ = 10⁹ Ω = 10³ MΩ.
About Nanoohms
The nanoohm (nΩ) equals 10⁻⁹ Ω, the same magnitude as the CGS-EMU abohm (1 abΩ = 10⁻⁹ Ω exactly). This scale is used for the lowest measurable resistances in copper busbars at cryogenic temperatures and in precision four-wire measurements of welded or crimped joints; the residual resistance of a high-quality solder joint on 2.5 mm² copper cable falls below 10 nΩ. 1 nΩ = 10⁻³ µΩ = 10⁻⁹ Ω.
