About Abamperes per square centimetre
The abampere per square centimetre (abA/cm²) is the current density unit of the CGS-EMU system, equal to 10 A / 10⁻⁴ m² = 10⁵ A/m². The abampere (= 10 A exactly) was the CGS-EMU base current unit before SI adoption; in EMU notation Ampère’s law uses J in abA/cm² and magnetic field in gauss without additional conversion factors. 1 abA/cm² = 10⁵ A/m² = 10 A/cm².
About Gigaamperes per square metre
The gigaampere per square metre (GA/m²) equals 10⁹ A/m², the extreme scale for thermonuclear plasmas and ultra-fast pulsed discharges. Current density in the compressed plasma of a z-pinch at peak compression is 1-100 GA/m²; field-emission current density from a sharp metallic tip at the Fowler-Nordheim threshold is ≈1-10 GA/m². 1 GA/m² = 10⁹ A/m² = 10³ MA/m².
