Millivolt to Microvolt conversion

1 mV = 1000 µVone millivolt in microvolts

1 µV = 0.001 mVone microvolt in millivolts

Millivolt (mV): One thousandth of a volt. Thermocouples and sensors output millivolts.

Microvolt (µV): One millionth of a volt. Used for EEG and radio receiver sensitivity.

How to convert millivolts to microvolts

To convert millivolts to microvolts, multiply the number of millivolts by 1000.

Formula

µV = mV × 1000

Examples

  • 5 mV = 5 × 1000 = 5000 µV
  • 25 mV = 25 × 1000 = 25000 µV
  • 100 mV = 100 × 1000 = 100000 µV

Frequently asked questions

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