1Ω

Rendered to 6 significant figures.

Formula

Formula
Ω = mΩ × 0.001

Multiply any value in milli-ohms by 0.001 to obtain the value in ohms.

Worked example

Convert 1000 to Ω.

  1. 01Start with 1000 mΩ.
  2. 02Multiply by the conversion factor: 1000 × 0.001 = 1 Ω.
Result1000 = 1 Ω

FAQ

What is the conversion factor from mΩ to Ω?
1 mΩ equals 0.001 Ω. To convert, multiply the value in milli-ohms by 0.001.
How do I convert 1 mΩ to Ω?
1 mΩ = 0.001 Ω. For any value, multiply by 0.001.
How do I convert Ω back to mΩ?
Divide by the same factor — or equivalently, multiply by 1000. So 1 Ω = 1000 mΩ.
When would I need to convert milli-ohm to ohm?
Resistance conversions between mΩ and Ω 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 Ω are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
