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.
Nanotesla (nT)
- Definition
- A nanotesla (nT) is one billionth of a tesla, also equal to one gamma.
- History
- Widely used in geophysics before the SI unit was established.
- Current use
- Magnetometers in archaeology, mineral exploration, and satellite missions report in nanotesla.
