Conversion Formula
A/m = GA/m × 1000000000
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 metre
The ampere per metre (A/m) is the SI coherent unit of magnetic field strength H, expressing the magnetomotive force per unit length. It defines how strongly a field drives magnetic flux through a material. Earth's geomagnetic H field is approximately 40-60 A/m; a typical transformer core operates at 100-1000 A/m. 1 A/m = 1 A m⁻¹.
