About Abamperes per square centimetre
The abampere per square centimetre (abA/cm²) is the current density unit of the CGS-EMU system, equal to 10 A / 10⁻⁴ m² = 10⁵ A/m². The abampere (= 10 A exactly) was the CGS-EMU base current unit before SI adoption; in EMU notation Ampère’s law uses J in abA/cm² and magnetic field in gauss without additional conversion factors. 1 abA/cm² = 10⁵ A/m² = 10 A/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.
