Conversion Formula
MA/m² = A/in² × 0.0015500031
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 Megaamperes per square metre
The megaampere per square metre (MA/m²) equals 10⁶ A/m², encountered in lightning channel physics and pulsed-power fusion devices. Peak current density in a lightning return-stroke channel is 10-100 MA/m²; plasma current sheets in z-pinch implosions reach 1-100 MA/m²; liquid-metal MHD pumps in fast reactors operate at 0.5-5 MA/m². 1 MA/m² = 10⁶ A/m² = 10³ kA/m².
