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 Picoamperes per metre
The picoampere per metre (pA/m) equals 10⁻¹² A/m. Encountered in magnetic anomaly detection (MAD) systems for submarine hunting, where the difference between Earth's background field and a submerged hull is measured with pA/m sensitivity; atomic magnetometers in zero-field NMR spectroscopy operate at this level. 1 pA/m = 10⁻¹² A/m = 10⁻³ nA/m.
