Magnetic field strength converter
H-field, not B-field. The oersted-to-A/m conversion carries a factor of 4π/1000, which is why magnet datasheets in mixed units are so easy to misread.

About magnetic field strength units
Convert A/m, kA/m, oersteds and kilooersteds.
H-field, not B-field. The oersted-to-A/m conversion carries a factor of 4π/1000, which is why magnet datasheets in mixed units are so easy to misread.
Dimensional formula: I L⁻¹. Every conversion on this page goes through the ampere per meter, using exact fractions rather than decimal approximations. Read how that works →
