Convert Gausses to Femtoteslas
Convert Gausses (G) to Femtoteslas (fT) instantly and accurately.
Conversion Formula
fT = G × 100000000000
About Gausses
The gauss (G) equals exactly 10⁻⁴ T, the CGS unit of magnetic flux density. Still widely used in magnetics engineering: permanent magnet remanence is typically 5 000-14 000 G for NdFeB; MRI field strengths are sometimes quoted as 10 000 G (1 T); loudspeaker gap fields are 8 000-20 000 G. 1 G = 10⁻⁴ T.
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.
