Convert Femtoteslas to Teslas
Convert Femtoteslas (fT) to Teslas (T) instantly and accurately.
Conversion Formula
T = fT × 1.000000000e-15
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 Teslas
The tesla (T) is the SI coherent unit of magnetic flux density, equal to 1 Wb/m² = 1 kg·s⁻²·A⁻¹. Clinical MRI scanners operate at 1.5-3 T; research MRI at 7-11.7 T; the strongest continuous electromagnet is 45 T (NHMFL); NdFeB remanence is about 1.0-1.4 T. 1 T = 10⁴ G = 1 Wb/m².
