Convert Gammas to Milliteslas
Convert Gammas (γ) to Milliteslas (mT) instantly and accurately.
Conversion Formula
mT = γ × 1.000000000e-6
About Gammas
The gamma (γ) equals exactly 1 nT = 10⁻⁹ T. A legacy CGS-adjacent unit adopted in geophysics and aeromagnetic surveying before SI. Total-field aeromagnetic surveys measure local anomalies of a few γ to thousands of γ over mineral deposits. 1 γ = 1 nT = 10⁻⁹ 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.
