Convert Gigaamperes per metre to Amperes per inch
Convert Gigaamperes per metre (GA/m) to Amperes per inch (A/in) instantly and accurately.
Conversion Formula
A/in = GA/m × 25400000
About Gigaamperes per metre
The gigaampere per metre (GA/m) equals 10⁹ A/m. Encountered only in extreme physics - neutron stars (magnetars) have surface fields of 10⁹-10¹¹ T, corresponding to GA/m to TA/m H-fields; plasma pinch experiments in z-pinch fusion drivers transiently achieve GA/m field strengths along the pinch axis. 1 GA/m = 10⁹ A/m.
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.
