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.

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.
