Convert Gigaamperes per metre to Amperes per foot
Convert Gigaamperes per metre (GA/m) to Amperes per foot (A/ft) instantly and accurately.
Conversion Formula
A/ft = GA/m × 304800000
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 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.
