How to convert microvolts to millivolts

To convert microvolts to millivolts, multiply the number of microvolts by 0.001.

Formula

mV = µV × 0.001

Examples

  • 5 µV = 5 × 0.001 = 0.005 mV
  • 25 µV = 25 × 0.001 = 0.025 mV
  • 100 µV = 100 × 0.001 = 0.1 mV

Frequently asked questions

How many millivolts are in one microvolt?
One microvolt is exactly 0.001 millivolts.
How do I convert millivolts to microvolts?
To convert millivolts to microvolts, multiply the number of millivolts by 1000. The formula is µV = mV × 1000.
Is this conversion exact?
Yes. Both units have exact definitions and the factor 0.001 is exact. Displayed results are only rounded when they have many decimal places.
Which is larger, a microvolt or a millivolt?
A millivolt is 1000 times larger than a microvolt. In other words, a microvolt is exactly 1/1000 of a millivolt.
