Conversion Formula

A/in = mA/m × 2.540000000e-5

About Milliamperes per metre

The milliampere per metre (mA/m) equals 10⁻³ A/m. Antenna near-field H-field measurements and EMC pre-compliance tests use mA/m; CISPR 14/16 and FCC Part 15 limit radiated field strength for consumer electronics in mA/m or equivalent dBµA/m at specified distances. 1 mA/m = 10⁻³ A/m = 10⁻³ Oe × (1000/4π).

About Amperes per inch

The ampere per inch (A/in) equals 1/0.0254 A/m ≈ 39.370 A/m. Standard unit in US magnetic core and inductor datasheets from manufacturers like Magnetics Inc. and Ferroxcube; B-H curves and core loss specifications for powder cores and ferrites are commonly plotted in Oe (H-axis) or A/in in North American catalogs. 1 A/in = 1/0.0254 A/m ≈ 39.37 A/m.
