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.
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.
