Conversion Formula
nΩ = TΩ × 1.000000000e+21
About Teraohms
The teraohm (TΩ) equals 10¹² Ω, the upper practical range of insulation resistance in laboratory and industrial measurements. Dry PTFE and fused quartz have volume resistivities of 10¹⁸ Ω·m or more, giving teraohm resistance for centimetre-thick samples; silicon photodiode dark resistance at room temperature can reach several TΩ; electrometer-grade guarded coaxial cables specify insulation resistance above 1 TΩ. 1 TΩ = 10¹² Ω = 10³ GΩ.
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.
