Formula
Formula
mΩ = µΩ × 0.001
Multiply any value in micro-ohms by 0.001 to obtain the value in milli-ohms.
Worked example
Convert 1000 µΩ to mΩ.
- 01Start with 1000 µΩ.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 mΩ.
Result1000 µΩ = 1 mΩ

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