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.
