About this tool
Convert teslas to milligauss instantly. Free, bidirectional, and fully in-browser.
1 tesla equals 10000000 milligauss — enter any tesla value to convert it to milligauss instantly. This Tesla to Milligauss converter is a client-side tool: it applies a single multiplication (mG = T × 10000000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert milligauss back to teslas. A reference table lists common tesla values already converted, and nothing you enter is sent to a server.
Open Tesla to Milligauss Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Tesla field.
Read the equivalent in milligauss in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert milligauss to teslas.
The result updates as you type, and the swap button flips the conversion to milligauss → tesla without reloading.
The conversion uses the precise factor (mG = T × 10000000), 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 tesla is 10000000 milligauss. Multiply the tesla value by 10000000 to convert. For example, 10 T = 100000000 mG.
mG = T × 10000000. This tool applies it automatically and shows a worked example: 10 T = 100000000 mG.
Yes. Press the swap button, or type into the milligauss field, and the tool converts milligauss to teslas using the inverse of the same relationship.
It uses the standard magnetic flux density definition (mG = T × 10000000), 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.
