Conversion Formula
pΩ = MΩ × 1.000000000e+18
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 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.
