About this tool
Convert millivolts to megavolts instantly. Free, bidirectional, and fully in-browser.
1 millivolt equals 1e-9 megavolts — enter any millivolt value to convert it to megavolts instantly. This Millivolt to Megavolt converter is a client-side tool: it applies a single multiplication (MV = mV × 1e-9) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert megavolts back to millivolts. A reference table lists common millivolt values already converted, and nothing you enter is sent to a server.
Open Millivolt to Megavolt Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Millivolt field.
Read the equivalent in megavolts in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert megavolts to millivolts.
The result updates as you type, and the swap button flips the conversion to megavolt → millivolt without reloading.
The conversion uses the precise factor (MV = mV × 1e-9), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
One millivolt is 1e-9 megavolts. Multiply the millivolt value by 1e-9 to convert. For example, 10 mV = 1e-8 MV.
MV = mV × 1e-9. This tool applies it automatically and shows a worked example: 10 mV = 1e-8 MV.
Yes. Press the swap button, or type into the megavolt field, and the tool converts megavolts to millivolts using the inverse of the same relationship.
It uses the standard electric potential definition (MV = mV × 1e-9), not a rounded approximation, so results are exact to the number of decimal places you select.
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.
