About these units

Gauss (G)

Definition
The gauss (G) is a CGS unit of magnetic flux density equal to 10⁻⁴ tesla.
History
Named after Carl Friedrich Gauss; it was the standard unit in the older CGS electromagnetic system.
Current use
Gauss is still widely used in industry for permanent magnets, MRI fringe fields, and legacy engineering documents.

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.
