To convert microvolts to millivolts, multiply by 0.001.
The calculation uses 1 µV = 0.001 mV. 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
value in mV = value in µV × 0.001
µV- Input unit: microvolts
mV- Output unit: millivolts
How to use this calculator
- Enter a value in µV.
- Multiply by the stored conversion factor.
- Read the result in mV; divide by the same factor to convert back.
Worked examples
Worked conversion
1 µV × 0.001 ≈ 0.001 mV.
Reverse conversion
0.001 mV ÷ 0.001 ≈ 1 µV. Rounding intermediate values can change the last displayed digit.
Frequently asked questions
What factor does this converter use?
It uses 0.001 mV per µV.
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.
