How many teslas are in one millitesla?

One millitesla equals exactly 0.001 teslas (1 mT = 10⁻³ T). The milli- prefix means one-thousandth, so dividing by 1000 gives you the value in teslas.

The tesla (T) is the SI unit of magnetic flux density (also called magnetic induction). It is defined as one weber per square meter (1 T = 1 Wb/m²). Strong MRI scanners typically operate between 1.5 T and 7 T.

When is the millitesla unit used?

Milliteslas are common for moderate magnetic fields such as those produced by permanent magnets, low-field MRI systems, magnetic sensors, and laboratory electromagnets. Earth's magnetic field is roughly 0.025–0.065 mT (25–65 microteslas).

How do I convert teslas back to milliteslas?

Multiply the tesla value by 1000. For example, 1.5 T × 1000 = 1500 mT. Use the swap button in this tool to perform the reverse conversion automatically.

How does millitesla relate to gauss?

1 mT = 10 gauss. The gauss is the CGS unit of magnetic flux density and is still common in older literature. 1 tesla = 10,000 gauss, so 1 millitesla = 10 gauss.
