nA/m = A/in × 39370078740
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 Nanoamperes per metre
The nanoampere per metre (nA/m) equals 10⁻⁹ A/m. Geomagnetic surveys for mineral exploration report spatial variations in Earth's field at nA/m resolution; optically pumped caesium and rubidium magnetometers used in archaeological prospection detect nA/m-scale buried structure anomalies. 1 nA/m = 10⁻⁹ A/m = 10⁻³ µA/m.
