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.
About Amperes per square inch
The ampere per square inch (A/in²) equals 1 / (0.0254)² A/m² ≈ 1550 A/m², used in US power semiconductor datasheets and electroforming specifications. JEDEC JESD22 and IPC standards specify maximum allowable current density in bond wires and copper interconnects in A/in²; electroforming of micro-components targets 0.5-5 A/in². 1 A/in² ≈ 1550 A/m² = 0.155 A/cm².
