Conversion Formula
nΩ = mΩ × 1000000
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.
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.
