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.

✓ Exact 1 A/m = 0.001 kA/m
As a fraction: 1/1000
1 A/m = 0.001 kA/m

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 →
