Convert Picoamperes per metre to Gigaamperes per metre
Convert Picoamperes per metre (pA/m) to Gigaamperes per metre (GA/m) instantly and accurately.
Conversion Formula
GA/m = pA/m × 1.000000000e-21
About Picoamperes per metre
The picoampere per metre (pA/m) equals 10⁻¹² A/m. Encountered in magnetic anomaly detection (MAD) systems for submarine hunting, where the difference between Earth's background field and a submerged hull is measured with pA/m sensitivity; atomic magnetometers in zero-field NMR spectroscopy operate at this level. 1 pA/m = 10⁻¹² A/m = 10⁻³ nA/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.
