FAQ
What is the conversion factor from mΩ to MΩ?
1 mΩ equals 1e-9 MΩ. To convert, multiply the value in milli-ohms by 1e-9.
How do I convert 1 mΩ to MΩ?
1 mΩ = 1e-9 MΩ. For any value, multiply by 1e-9.
How do I convert MΩ back to mΩ?
Divide by the same factor — or equivalently, multiply by 1e+9. So 1 MΩ = 1e+9 mΩ.
When would I need to convert milli-ohm to mega-ohm?
Resistance conversions between mΩ 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?
Yes. Both mΩ and MΩ are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
