Nanotesla (nT)
The nanotesla is one billionth of a tesla. In geophysics it is also called the gamma (γ).
Symbol: nT
Quantity: magnetic flux density (B field)
SI relation: 1 nT = 1 × 10⁻⁹ T (exact)
Derivation: 1 nT = 10⁻⁹ T (also called a gamma in geophysics)
Exact: yes, by definition
Typical uses
- Geomagnetic surveys and magnetometers
- Space weather and geomagnetic storm reports
- Mineral exploration
