About Amperes per square metre
The ampere per square metre (A/m²) is the SI coherent unit of current density, defined as 1 A flowing through 1 m² cross-section. Electrolytic copper plating baths operate at 200-500 A/m²; photovoltaic short-circuit current density of silicon solar cells at AM 1.5G is 35-42 A/m²; cathodic protection of bare steel in soil applies 10-50 A/m². 1 A/m² = 0.1 mA/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.
