Conversion Formula
TΩ = GΩ × 0.001
About Gigaohms
The gigaohm (GΩ) equals 10⁹ Ω, the regime of PTFE and glass insulation, MOSFET gate oxide, and specialised electrometer inputs. High-quality PCB insulation resistance between adjacent tracks exceeds 10 GΩ; the reverse-leakage resistance of a silicon junction at room temperature is in the gigaohm range; the guarded input of a Keithley 6517B electrometer is rated at 200 TΩ, but JFET-input op-amps commonly show input resistance of a few GΩ. 1 GΩ = 10⁹ Ω = 10³ MΩ.
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.
