About this tool
Millivolt to Volt Converter
Convert millivolts to volts instantly. Free, bidirectional, and fully in-browser.
1 millivolt equals 0.001 volts — enter any millivolt value to convert it to volts instantly. This Millivolt to Volt converter is a client-side tool: it applies a single multiplication (V = mV × 0.001) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert volts back to millivolts. A reference table lists common millivolt values already converted, and nothing you enter is sent to a server.
How to use Millivolt to Volt Converter
- 1
Open Millivolt to Volt Converter on AltFTool — it loads instantly in your browser.
- 2
Type the value you want to convert into the Millivolt field.
- 3

- 4
Use the decimal-places slider for more or less precision, or press swap to convert volts to millivolts.
Why use Millivolt to Volt Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to volt → millivolt without reloading.
Exact Voltage math
The conversion uses the precise factor (V = mV × 0.001), so the number matches a manual calculation to the decimal places you choose.
Adjustable precision
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Private and free
Everything runs locally in your browser — no upload, no account, no limit on conversions.
Common use cases
- Converting a millivolt measurement to volts for a spec, listing, or report.
- Checking millivolt↔volt figures while comparing products, datasets, or documentation.
- Learning the millivolt-to-volt relationship from the worked formula and the common-value table.
Frequently asked questions
How many volts are in a millivolt?
One millivolt is 0.001 volts. Multiply the millivolt value by 0.001 to convert. For example, 10 mV = 0.01 V.
What is the formula to convert millivolts to volts?
V = mV × 0.001. This tool applies it automatically and shows a worked example: 10 mV = 0.01 V.
Can it convert volts back to millivolts?
Yes. Press the swap button, or type into the volt field, and the tool converts volts to millivolts using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard electric potential definition (V = mV × 0.001), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
