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 Femtoteslas

The femtotesla (fT) equals 10⁻¹⁵ T. The standard field scale for biomagnetic measurements: neural signals in magnetoencephalography (MEG) produce cortical fields of 10-1000 fT, while cardiac magnetic fields (magnetocardiography, MCG) are around 10-100 pT. SQUID sensors routinely measure in the fT range. 1 fT = 10⁻¹⁵ T.
