mG = γ × 0.01

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 Milligausses

The milligauss (mG) equals 10⁻⁷ T. The dominant unit in EMF (electromagnetic field) health and safety assessments: ICNIRP and IEEE C95.1 reference levels for power-frequency (50/60 Hz) public exposure limits are expressed in mG or µT; typical residential power-line exposure is 0.2-5 mG. 1 mG = 10⁻⁷ T = 0.1 µT.
