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.
About Kiloamperes per square metre
The kiloampere per square metre (kA/m²) equals 10³ A/m², the scale for aluminium smelting, high-rate electroplating, and bus bar design. Hall-Heroult aluminium reduction cells operate at 3-10 kA/m²; electric arc furnace graphite electrodes carry 50-150 kA/m²; allowable current density in copper bus bars for switchgear is 1-3 kA/m². 1 kA/m² = 10³ A/m² = 100 mA/cm².
