Conversion Formula
pΩ = mΩ × 1000000000
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 Picoohms
The picoohm (pΩ) equals 10⁻¹² Ω, used for ultra-low resistance measurements in superconductors and precision four-wire metrology. A superconducting wire transitioning through its critical temperature shows residual resistance at the picoohm level; high-precision Josephson-array resistance bridges operated at national metrology institutes resolve differences below 1 pΩ. 1 pΩ = 10⁻³ nΩ = 10⁻¹² Ω.
