To convert ohms to milliohms, multiply by 1000.
The calculation uses 1 Ω = 1000 mΩ. Results are displayed to at most 10 significant digits. Definitions can be exact while a displayed decimal is rounded. Match the displayed precision to your original measurement.
The formula
Ω- Input unit: ohms
mΩ- Output unit: milliohms
How to use this calculator
- Enter a value in Ω.
- Multiply by the stored conversion factor.
- Read the result in mΩ; divide by the same factor to convert back.
Worked examples
Worked conversion
1 Ω × 1000 ≈ 1000 mΩ.
Reverse conversion
1000 mΩ ÷ 1000 ≈ 1 Ω. Rounding intermediate values can change the last displayed digit.
Frequently asked questions
What factor does this converter use?
It uses 1000 mΩ per Ω.
Why can another converter show a slightly different answer?
Check the unit convention first (such as US versus Imperial or decimal versus binary), then compare rounding. Measurement uncertainty is separate from the unit conversion.
