Unit definition
Microvolts (µV) One microvolts equals 0.000001 volt.
Unit history
Microvolts is represented here using its modern SI definition or an internationally accepted relationship to an SI base unit.
Step by step
1. Parse the value, including fractions.
2. Convert µV to volt.
3. Convert the base value to mV and apply your display precision.
Understand the result before using it
Microvolts to Millivolts converts a value measured in Microvolts (µV) into the equivalent value in Millivolts (mV). The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
result = input × 0.000001 ÷ 0.001
Assumptions
- Microvolts and Millivolts represent the same voltage quantity.
- The input is expressed in µV; the output is expressed in mV.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 µV = 0.001 mV. For another value, apply the same relationship and round only to the precision your source measurement supports.
When to use it
Good uses
- Read a µV measurement in a document that expects mV.
- Compare a microvolts value with a value reported in millivolts.
- Check the µV to mV arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- Do not confuse µV with another unit that has a similar name or symbol.
- Round the output to a precision justified by the original measurement.
- Verify safety-critical, regulated, laboratory, and contractual conversions against the controlling standard.

Questions about this calculation
How do I convert Microvolts to Millivolts?
result = input × 0.000001 ÷ 0.001. Input is in µV; result is in mV. 1 µV = 0.001 mV. The displayed digits may be rounded.
What is 1 µV in mV?
1 µV = 0.001 mV. The displayed digits may be rounded.
Can I reverse the µV to mV conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts mV back to µV.
Is the Microvolts to Millivolts result exact?
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
