Conversion Formula
GΩ = abΩ × 1.000000000e-18
About Abohms
The abohm (abΩ) is the resistance unit of the CGS-EMU system, defined as 1 abvolt per abampere = 10⁻⁸ V / 10 A = 10⁻⁹ Ω, exactly equal to 1 nΩ. It appears in nineteenth- and early-twentieth-century electromagnetic engineering texts for low-resistance measurements of copper conductors, motor windings, and cable joints. 1 abΩ = 10⁻⁹ Ω = 1 nΩ.
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.
