Convert Kiloamperes per metre to Amperes per inch
Convert Kiloamperes per metre (kA/m) to Amperes per inch (A/in) instantly and accurately.
Conversion Formula
A/in = kA/m × 25.4
About Kiloamperes per metre
The kiloampere per metre (kA/m) equals 10³ A/m. The primary practical unit for strong magnetic fields - MRI scanner bore fields of 1-3 T correspond to 800 kA/m-2.4 MA/m in free space; coercivity of hard ferrite permanent magnets (ceramic) is 150-300 kA/m; NdFeB magnets have coercivity 900-2000 kA/m. 1 kA/m = 10³ A/m ≈ 12.566 Oe.
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.
