Convert Teraohms to Microohms
Convert Teraohms (TΩ) to Microohms (µΩ) instantly and accurately.
Conversion Formula
µΩ = TΩ × 1.000000000e+18
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 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.
