About Nanoteslas

The nanotesla (nT) equals 10⁻⁹ T. The standard unit in geomagnetism and space physics: Earth's surface field is 25 000-65 000 nT; geomagnetic storms cause fluctuations of hundreds to thousands of nT; solar wind field at 1 AU is 2-10 nT. 1 nT = 10⁻⁹ T = 1 γ.

About Milliteslas

The millitesla (mT) equals 10⁻³ T = 10 G. Used in industrial induction heating, magnetic particle inspection (MPI), and low-field MRI systems; the fringe field at the 5 G (0.5 mT) safety line around clinical MRI scanners is the standard exclusion boundary. 1 mT = 10⁻³ T = 10 G.
