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 Amperes per square centimetre
The ampere per square centimetre (A/cm²) equals 10⁴ A/m², the standard current density unit for power electronics, arc physics, and high-performance batteries. Bipolar junction transistor saturation current density is 0.5-5 A/cm²; vacuum arc contact spots on copper carry 100-1000 A/cm²; fast-charge lithium-ion cathodes support up to 0.05 A/cm². 1 A/cm² = 10⁴ A/m² = 10 kA/m².
