About Kiloamperes per square metre
The kiloampere per square metre (kA/m²) equals 10³ A/m², the scale for aluminium smelting, high-rate electroplating, and bus bar design. Hall-Heroult aluminium reduction cells operate at 3-10 kA/m²; electric arc furnace graphite electrodes carry 50-150 kA/m²; allowable current density in copper bus bars for switchgear is 1-3 kA/m². 1 kA/m² = 10³ A/m² = 100 mA/cm².
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.
