Convert Gigaohms to Milliohms
Convert Gigaohms (GΩ) to Milliohms (mΩ) instantly and accurately.
Conversion Formula
mΩ = GΩ × 1000000000000
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 Milliohms
The milliohm (mΩ) equals 10⁻³ Ω, the scale of precision current-sensing shunts, relay contacts, and PCB trace resistance. Current-sensing shunts of 1-10 mΩ allow high-current measurement by detecting the millivolt drop they produce; electrical continuity standards flag connections above a few milliohms; DC winding resistance of large motor coils is typically 0.1-10 mΩ. 1 mΩ = 10⁻³ Ω = 10³ µΩ.
