Convert Milliamperes per metre to Gigaamperes per metre
Convert Milliamperes per metre (mA/m) to Gigaamperes per metre (GA/m) instantly and accurately.
Conversion Formula
GA/m = mA/m × 1.000000000e-12
About Milliamperes per metre
The milliampere per metre (mA/m) equals 10⁻³ A/m. Antenna near-field H-field measurements and EMC pre-compliance tests use mA/m; CISPR 14/16 and FCC Part 15 limit radiated field strength for consumer electronics in mA/m or equivalent dBµA/m at specified distances. 1 mA/m = 10⁻³ A/m = 10⁻³ Oe × (1000/4π).
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.
