Millivolts (mV) One millivolts equals 0.001 volt.
Unit history
Millivolts 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 mV to volt.
3. Convert the base value to µV and apply your display precision.
Understand the result before using it
Millivolts to Microvolts converts a value measured in Millivolts (mV) into the equivalent value in Microvolts (µV). 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 × 0.001 ÷ 0.000001
Assumptions
- Millivolts and Microvolts represent the same voltage quantity.
- The input is expressed in mV; the output is expressed in µV.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 mV = 1,000 µV. 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 mV measurement in a document that expects µV.
- Compare a millivolts value with a value reported in microvolts.
- Check the mV-to-µV arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- Do not confuse mV 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 Millivolts to Microvolts?
result = input × 0.001 ÷ 0.000001 Using the displayed relationship, 1 mV equals 1,000 µV.
How many Microvolts are in one Millivolts?
One Millivolts is 1,000 Microvolts. The displayed digits may be rounded.
Can I reverse the mV to µV conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts µV back to mV.
Is the Millivolts to Microvolts 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.
