Oersted (Oe)
Definition: The oersted is the unit of magnetic field strength in the CGS (centimeter-gram-second) system of units.
History/origin: Named in honor of Hans Christian Ørsted. It was the primary unit of magnetic strength before the international SI system (A/m) became the official standard.
Current use: Still widely used in North America and in the field of permanent magnet manufacturing and materials science.
Kiloampere/meter (kA/m)
Definition: A kiloampere per meter is a multiple of the SI unit, equal to one thousand amperes per meter.
History/origin: As industrial magnets and motors grew in power, using large numbers in A/m became impractical, leading to the adoption of the kilo- prefix.
Current use: Standard unit for describing the magnetic field intensity in high-power industrial equipment, electric vehicle motors, and MRI scanners.

How to Convert Oersted (Oe) to Kiloampere/meter (kA/m)
1 oe = 0.07957747 ka_m
1 ka_m = 12.56637086 oe
Example: convert 15 oe to ka_m:
15 oe = 15 × 0.07957747 ka_m = 1.19366205 ka_m
Did You Know?
- The Oersted (Oe) is named after Hans Christian Ørsted, who accidentally discovered in 1820 that an electric current could move a compass needle, proving electricity and magnetism are linked!
- Kiloampere per meter (kA/m) is used to describe very powerful magnetic fields, such as those found inside industrial power generators and MRI machines.
