FAQ
What is the conversion factor from MΩ to GΩ?
1 MΩ equals 0.001 GΩ. To convert, multiply the value in mega-ohms by 0.001.
How do I convert 1 MΩ to GΩ?
1 MΩ = 0.001 GΩ. For any value, multiply by 0.001.
How do I convert GΩ back to MΩ?
Divide by the same factor — or equivalently, multiply by 1000. So 1 GΩ = 1000 MΩ.
When would I need to convert mega-ohm to giga-ohm?
Resistance conversions between MΩ and GΩ 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).
