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.

About Microteslas

The microtesla (µT) equals 10⁻⁶ T. Earth's surface magnetic field is approximately 25-65 µT; the WHO recommends 100 µT as an occupational limit for 50/60 Hz fields; metal detectors and electromagnetic compatibility (EMC) tests routinely work in the µT range. 1 µT = 10⁻⁶ T = 10 mG.
