FAQ
What is the conversion factor from GΩ to mΩ?
1 GΩ equals 1e+12 mΩ. To convert, multiply the value in giga-ohms by 1e+12.
How do I convert 1 GΩ to mΩ?
1 GΩ = 1e+12 mΩ. For any value, multiply by 1e+12.
How do I convert mΩ back to GΩ?
Divide by the same factor — or equivalently, multiply by 1e-12. So 1 mΩ = 1e-12 GΩ.
When would I need to convert giga-ohm to milli-ohm?
Resistance conversions between GΩ and mΩ are used in electrical-network analysis, instrumentation (RTD/thermistor specification), grounding and bonding measurements, and electronics design. Ohms cover most circuit calculations; kΩ and MΩ appear in input-impedance specs, while milli-ohms cover bus-bar joints and shunt resistors.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
