Teslas to Milliteslas Converter T → mT
1 tesla (T) = 1000 milliteslas (mT). Type a value below — the conversion happens instantly, entirely on your device.
1 T = 1000 mT
1 teslas = 1000 milliteslas
1 × 1000 = 1000
1 T equals 1000 mT, so multiplying by 1000 converts the value. The result describes the exact same quantity — only the measuring stick changes.
How to convert teslas to milliteslas
milliteslas = teslas × 1000 — multiply the tesla value by 1000.
Example: 10 T = 10,000 mT.
To convert the other way: teslas = milliteslas ÷ 1000

About the units
What is a tesla?
The SI unit of magnetic flux density. A fridge magnet is a few millitesla; an MRI scanner runs at 1.5–3 T. Earth's field is only about 50 microtesla.
What is a millitesla?
One-thousandth of a tesla (10⁻³ T), equal to 10 gauss. Handy for everyday magnets, which sit in the single-to-hundreds of millitesla range.
Frequently asked questions
How many milliteslas are in 1 tesla?
1 tesla (T) = 1000 milliteslas (mT).
What is the formula to convert teslas to milliteslas?
milliteslas = teslas × 1000 — multiply the tesla value by 1000.
How do I convert T to mT without a calculator?
Multiply by 1000 for a close estimate. Exact factor: 1 T = 1000 mT.
Is this T-to-mT converter accurate and private?
Yes. It uses the exact internationally defined conversion factors and computes results locally in your browser — your input is never sent to a server, and the page keeps working offline.
