Oersted is the CGS system unit of magnetic field strength. The equivalent SI unit is Ampere-turn/metre, and 1 Oersted = 1000/4π or 79.58 Ampere-turns/metre.
The oersted (/ˈɜːrstɛd/,; symbol Oe) is the coherent derived unit of the auxiliary magnetic field H in the centimetre–gram–second system of units (CGS). It is equivalent to 1 dyne per maxwell.
