Convert Femtoamperes per metre to Gigaamperes per metre
Convert Femtoamperes per metre (fA/m) to Gigaamperes per metre (GA/m) instantly and accurately.
Conversion Formula
GA/m = fA/m × 1.000000000e-24
About Femtoamperes per metre
The femtoampere per metre (fA/m) equals 10⁻¹⁵ A/m. Used in SQUID (superconducting quantum interference device) magnetometer research to characterise noise floors in ultra-sensitive magnetic field measurements; the Earth's geomagnetic DC drift and biomagnetic fields from neurons produce field gradients at the fA/m level in heavily shielded rooms. 1 fA/m = 10⁻¹⁵ A/m.
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.
