Convert Gigaohms to Microohms
Convert Gigaohms (GΩ) to Microohms (µΩ) instantly and accurately.
Conversion Formula
µΩ = GΩ × 1000000000000000
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 Microohms
The microohm (µΩ) equals 10⁻⁶ Ω, the practical scale for contact resistance testing, bus-bar joints, and circuit-breaker contacts. A well-made bolted bus-bar connection has contact resistance below 50 µΩ; a 25 mm² copper conductor has resistance of about 0.7 µΩ/mm; IEC 60947 specifies acceptance limits for switchgear contacts in microohms. 1 µΩ = 10⁻³ mΩ = 10³ nΩ.
