Microvolts to Millivolts Converter
Convert microvolt to millivolt instantly. 1 µV = 0.001 mV, worked steps and a full reference table.
How to use it
- Type the value in microvolt — the result updates as you type.
- Use Swap to flip the direction, or change either dropdown to convert between any two units.
- Click the result to copy it. The URL updates too, so you can bookmark or share the exact conversion.
Examples
| 1 µV | 0.001 mV |
| 5 µV | 0.005 mV |
| 10 µV | 0.01 mV |
| 100 µV | 0.1 mV |
One microvolt equals 0.001 millivolts (mV). To convert microvolts to millivolts, multiply by 0.001; to go back the other way, multiply by 1000 instead.
The converter above does it as you type and shows the working underneath, so you can check the arithmetic rather than take the number on trust.
What microvolts and millivolts actually measure
Microvolt (µV) — A microvolt is a millionth of a volt. Biomedical signals such as EEG, and sensitive instrumentation.
Millivolt (mV) — A millivolt is a thousandth of a volt. Thermocouples, sensor outputs and ECG traces.

The most common values, worked out in advance. Anything not listed can be typed straight into the converter.
| µV | mV |
|---|---|
| 1 µV | 0.001 mV |
| 2 µV | 0.002 mV |
| 5 µV | 0.005 mV |
| 10 µV | 0.01 mV |
| 25 µV | 0.025 mV |
| 50 µV | 0.05 mV |
| 100 µV | 0.1 mV |
How to convert microvolts to millivolts by hand
Multiply the number of microvolts by 0.001.
For example, 25 µV × 0.001 = 0.025 mV.
Going the other way, divide by 0.001 — or multiply by 1000, which is the same thing and easier to do in your head.
Everything runs in your browser
There is no server involved in the calculation. The numbers you type never leave your device, nothing is logged, and the page keeps working with no connection once it has loaded. That is not a marketing line — it is simply how the tool is built, because a calculation like this has no reason to touch a network.
Questions people ask
How many mV are in 1 µV?
1 µV equals exactly 0.001 mV. Multiply any value in microvolt by 0.001 to get millivolt.
Is anything uploaded to a server?
No. The whole calculation happens in your browser. Nothing is sent anywhere, and the page keeps working offline once loaded.
