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 Megaoersteds
The megaoersted (MOe) equals 10⁹/(4π) A/m ≈ 7.958 × 10⁷ A/m. Encountered in ultra-high-field pulsed magnet research - National High Magnetic Field Laboratory (NHMFL) 100 T pulsed fields correspond to ≈1 MOe; internal crystalline fields at magnetic rare-earth sites in hyperfine studies are of this order. 1 MOe = 10⁹/(4π) A/m.
