How to Convert Gammas to Oersteds
The gamma and oersted are both units of magnetic field. By definition, 1 oersted equals exactly 79577500000 gammas. This means to convert gammas to oersteds, you divide by 79577500000.
Formula
Step-by-Step Example
Convert 5 γ to oersteds:
We need to convert gammas to oersteds
Since 1 Oe = 79577500000 γ, divide by 79577500000
5 ÷ 79577500000 = 6.2831830605e-11
5 γ = 6.2831830605e-11 Oe

About These Units
Gamma (γ)
The gamma (γ) equals exactly 1 nanotesla (10⁻⁹ T). Traditional unit in geophysics and aeromagnetic surveys. Earth's field: 25,000-65,000 γ. Magnetic anomalies for mineral exploration measured in gammas. Largely replaced by nanotesla in modern usage.
Oersted (Oe)
The oersted (Oe) is the CGS unit of magnetic field intensity (H-field), not flux density (B-field). In vacuum/air, 1 Oe ≈ 79.58 A/m. Related to gauss through permeability: B(G) = μ × H(Oe). Named after Hans Christian Ørsted.
