Convert Picoohms to Microohms
Convert Picoohms (pΩ) to Microohms (µΩ) instantly and accurately.
Conversion Formula
µΩ = pΩ × 1.000000000e-6
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 Microohms
The microohm (µΩ) equals 10⁻⁶ Ω, the practical scale for contact resistance testing, bus-bar joints, and circuit-breaker contacts. A well-made bolted bus-bar connection has contact resistance below 50 µΩ; a 25 mm² copper conductor has resistance of about 0.7 µΩ/mm; IEC 60947 specifies acceptance limits for switchgear contacts in microohms. 1 µΩ = 10⁻³ mΩ = 10³ nΩ.
