About these units

Tesla (T)

Definition
The tesla (T) is the SI unit of magnetic flux density, equal to one weber per square meter or one volt·second per square meter.
History
Named after inventor Nikola Tesla, it was adopted by the CGPM in 1960.
Current use
MRI scanners operate at 1.5–3 T; research magnets reach tens of tesla. It is the standard unit in electromagnetism and medical imaging.

Millitesla (mT)

Definition
A millitesla (mT) is one thousandth of a tesla.
History
A metric sub-multiple of the tesla.
Current use
Millitesla values describe permanent magnets and therapeutic magnetic-field devices.
