About this tool
Convert milliteslas to teslas instantly. Free, bidirectional, and fully in-browser.
1 millitesla equals 0.001 teslas — enter any millitesla value to convert it to teslas instantly. This Millitesla to Tesla converter is a client-side tool: it applies a single multiplication (T = mT × 0.001) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert teslas back to milliteslas. A reference table lists common millitesla values already converted, and nothing you enter is sent to a server.
Open Millitesla to Tesla Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Millitesla field.
Read the equivalent in teslas in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert teslas to milliteslas.
The result updates as you type, and the swap button flips the conversion to tesla → millitesla without reloading.
The conversion uses the precise factor (T = mT × 0.001), 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 millitesla is 0.001 teslas. Multiply the millitesla value by 0.001 to convert. For example, 10 mT = 0.01 T.
T = mT × 0.001. This tool applies it automatically and shows a worked example: 10 mT = 0.01 T.
Yes. Press the swap button, or type into the tesla field, and the tool converts teslas to milliteslas using the inverse of the same relationship.
It uses the standard magnetic flux density definition (T = mT × 0.001), 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.
