Tesla to Millitesla Converter
Convert teslas to milliteslas instantly. Free, bidirectional, and fully in-browser.
1 tesla equals 1000 milliteslas — enter any tesla value to convert it to milliteslas instantly. This Tesla to Millitesla converter is a client-side tool: it applies a single multiplication (mT = T × 1000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert milliteslas back to teslas. A reference table lists common tesla values already converted, and nothing you enter is sent to a server.

Why use Tesla to Millitesla Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to millitesla → tesla without reloading.
Exact Magnetic Flux Density math
The conversion uses the precise factor (mT = T × 1000), 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 tesla measurement to milliteslas for a spec, listing, or report.

- Learning the tesla-to-millitesla relationship from the worked formula and the common-value table.
Frequently asked questions
How many milliteslas are in a tesla?
One tesla is 1000 milliteslas. Multiply the tesla value by 1000 to convert. For example, 10 T = 10000 mT.
What is the formula to convert teslas to milliteslas?
mT = T × 1000. This tool applies it automatically and shows a worked example: 10 T = 10000 mT.
Can it convert milliteslas back to teslas?
Yes. Press the swap button, or type into the millitesla field, and the tool converts milliteslas to teslas using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard magnetic flux density definition (mT = T × 1000), 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.
