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 Milliamperes per square metre
The milliampere per square metre (mA/m²) equals 10⁻³ A/m². Cathodic protection current density applied to reinforced concrete structures is 2-20 mA/m²; faradaic current density during slow anodic dissolution of iron in dilute H2SO4 is 1-100 mA/m²; exchange current density of the oxygen reduction reaction on platinum is ≈2 mA/m². 1 mA/m² = 10⁻³ A/m² = 0.1 µA/cm².
