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.
About Millioersteds
The millioersted (mOe) equals 1/(4π) A/m ≈ 79.577 mA/m. Used in magnetic recording media characterisation - remanent coercivity of flexible magnetic media (floppy disks, cassette tape) is often cited in mOe in legacy test standards; sensitive fluxgate magnetometers report data in mOe in older geomagnetic survey literature. 1 mOe = 1/(4π) A/m ≈ 0.07958 A/m.
