Convert Femtoteslas to Milliteslas
Convert Femtoteslas (fT) to Milliteslas (mT) instantly and accurately.
Conversion Formula
mT = fT × 1.000000000e-12
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 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.
