About Microamperes per square metre
The microampere per square metre (µA/m²) equals 10⁻⁶ A/m². Corrosion current density of carbon steel in neutral deaerated water is 0.1-100 µA/m²; exchange current density of the Zn/Zn2+ electrode is ≈20 µA/m²; cathodic protection criterion current density for buried steel pipelines in low-resistivity soil is 2-20 µA/m². 1 µA/m² = 10⁻⁶ A/m² = 10⁻³ 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.
