About Ohms
The ohm (Ω) is the SI derived unit of electrical resistance, equal to 1 volt per ampere (1 V/A = 1 kg·m²·A⁻²·s⁻³), named after Georg Simon Ohm who published V = IR in 1827. Common benchmarks: a standard earphone is 32 Ω, a coaxial cable has 50 or 75 Ω characteristic impedance, and a typical carbon-film resistor spans 1 Ω to 10 MΩ. The ohm is realised internationally via the quantum Hall resistance standard Rₖ = h/e² ≈ 25 812.807 Ω.
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.
