How to Convert Oersteds to Milliteslas

The oersted and millitesla are both units of magnetic field. 1 millitesla equals 12566.366121 oersteds. This means to convert oersteds to milliteslas, you divide by 12566.366121.

Formula

milliteslas = oersteds ÷ 12566.366121

Step-by-Step Example

Convert 5 Oe to milliteslas:

1
Convert 5 Oe to milliteslas

We need to convert oersteds to milliteslas

2
Apply the formula

Since 1 mT = 12566.366121 Oe, divide by 12566.366121

5 ÷ 12566.366121 = 0.0003978875

Answer

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.
