Formula
Step-by-Step Example
Convert 5 Oe to milliteslas:
We need to convert oersteds to milliteslas
Since 1 mT = 12566.366121 Oe, divide by 12566.366121
5 ÷ 12566.366121 = 0.0003978875
5 Oe = 0.0003978875 mT

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.
Millitesla (mT)
A millitesla (mT) equals 0.001 teslas or 10 gauss. Common range for permanent magnets: fridge magnet 5 mT, speaker magnet 100-400 mT, hard drive head 10-50 mT. Used in electronics, medical devices, and magnetic sensors.
