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 Milligausses

The milligauss (mG) equals 10⁻⁷ T. The dominant unit in EMF (electromagnetic field) health and safety assessments: ICNIRP and IEEE C95.1 reference levels for power-frequency (50/60 Hz) public exposure limits are expressed in mG or µT; typical residential power-line exposure is 0.2-5 mG. 1 mG = 10⁻⁷ T = 0.1 µT.
