About Amperes per foot
The ampere per foot (A/ft) equals 1/0.3048 A/m ≈ 3.281 A/m. Used in US electromagnetic coil design and transformer winding specifications where dimensions are in feet; older US Navy and DoD magnetic shielding specifications for shipboard demagnetisation state H values in A/ft. 1 A/ft = 1/0.3048 A/m ≈ 3.2808 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.
