Millivolts to Microvolts Converter
Convert millivolt to microvolt instantly. 1 mV = 1000 µV, worked steps and a full reference table.
How to use it
- Type the value in millivolt — 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 mV | 1000 µV |
| 5 mV | 5000 µV |
| 10 mV | 10000 µV |
| 100 mV | 100000 µV |
One millivolt equals 1000 microvolts (µV). To convert millivolts to microvolts, multiply by 1000; to go back the other way, multiply by 0.001 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 millivolts and microvolts actually measure
Millivolt (mV) — A millivolt is a thousandth of a volt. Thermocouples, sensor outputs and ECG traces.
Microvolt (µV) — A microvolt is a millionth of a volt. Biomedical signals such as EEG, and sensitive instrumentation.

| mV | µV |
|---|---|
| 1 mV | 1000 µV |
| 2 mV | 2000 µV |
| 5 mV | 5000 µV |
| 10 mV | 10000 µV |
| 25 mV | 25000 µV |
| 50 mV | 50000 µV |

How to convert millivolts to microvolts by hand
Multiply the number of millivolts by 1000.
For example, 25 mV × 1000 = 25000 µV.
Going the other way, divide by 1000 — or multiply by 0.001, 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 µV are in 1 mV?
1 mV equals exactly 1000 µV. Multiply any value in millivolt by 1000 to get microvolt.
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.
