How to Convert Oersteds to Milligauss
The oersted and milligauss are both units of magnetic field. 1 milligauss equals 1.2566366121 oersteds. This means to convert oersteds to milligauss, you divide by 1.2566366121.
Formula
Step-by-Step Example
Convert 5 Oe to milligauss:
We need to convert oersteds to milligauss
Since 1 mG = 1.2566366121 Oe, divide by 1.2566366121
5 ÷ 1.2566366121 = 3.978875
5 Oe = 3.978875 mG

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.
Milligauss (mG)
A milligauss (mG) equals 0.001 gauss or 0.1 microtesla. Used for environmental magnetic field measurements. Power lines: 1-100 mG at distance. Computer monitors: 1-25 mG. Background urban level: 0.5-4 mG. EMF meters often display milligauss.
