Conversion Formula
MΩ = GΩ × 1000
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 Megaohms
The megaohm (MΩ) equals 10⁶ Ω, the scale of insulation testing and high-impedance analogue circuit design. Insulation testers (meggers) measure cable and motor winding insulation from 0.1-1000 MΩ; pH electrode output impedance is 10-500 MΩ; precision op-amp feedback networks use 1-10 MΩ resistors to set very high signal-source impedance. 1 MΩ = 10⁶ Ω = 10³ kΩ.
