nΩ = MΩ × 1000000000000000
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.
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.
