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.
About Amperes per square foot
The ampere per square foot (A/ft²) equals 1 / (0.3048)² A/m² ≈ 10.764 A/m², used in US electroplating and grounding standards. ASTM B734 copper plating specifications cite current density in A/ft²; IEEE Std 80 specifies grounding grid design current density in A/ft² when ground fault current is distributed across the soil surface. 1 A/ft² ≈ 10.764 A/m².
