About Nanoohms
The nanoohm (nΩ) equals 10⁻⁹ Ω, the same magnitude as the CGS-EMU abohm (1 abΩ = 10⁻⁹ Ω exactly). This scale is used for the lowest measurable resistances in copper busbars at cryogenic temperatures and in precision four-wire measurements of welded or crimped joints; the residual resistance of a high-quality solder joint on 2.5 mm² copper cable falls below 10 nΩ. 1 nΩ = 10⁻³ µΩ = 10⁻⁹ Ω.
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.
