How to Convert Oersteds to Gammas
The oersted and gamma are both units of magnetic field. By definition, 1 oersted equals exactly 79577500000 gammas. This means to convert oersteds to gammas, you multiply by 79577500000.
Formula
Step-by-Step Example
Convert 5 Oe to gammas:
We need to convert oersteds to gammas
Since 1 Oe = 79577500000 γ, multiply by 79577500000
5 × 79577500000 = 397887500000
5 Oe = 397887500000 γ

About These Units
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.
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.
