Conversion Formula
abΩ = pΩ × 0.001
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.
About Abohms
The abohm (abΩ) is the resistance unit of the CGS-EMU system, defined as 1 abvolt per abampere = 10⁻⁸ V / 10 A = 10⁻⁹ Ω, exactly equal to 1 nΩ. It appears in nineteenth- and early-twentieth-century electromagnetic engineering texts for low-resistance measurements of copper conductors, motor windings, and cable joints. 1 abΩ = 10⁻⁹ Ω = 1 nΩ.
