Convert Femtoteslas to Megateslas
Convert Femtoteslas (fT) to Megateslas (MT) instantly and accurately.
Conversion Formula
MT = fT × 1.000000000e-21
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 Megateslas
The megatesla (MT) equals 10⁶ T. Relevant only in astrophysics - neutron star (magnetar) surface fields reach 10⁸-10¹¹ T (0.1-100 000 MT); laser-driven implosion experiments have produced fields approaching 0.001 MT transiently. 1 MT = 10⁶ T = 10¹⁰ G.
