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 Milliamperes per square metre
The milliampere per square metre (mA/m²) equals 10⁻³ A/m². Cathodic protection current density applied to reinforced concrete structures is 2-20 mA/m²; faradaic current density during slow anodic dissolution of iron in dilute H2SO4 is 1-100 mA/m²; exchange current density of the oxygen reduction reaction on platinum is ≈2 mA/m². 1 mA/m² = 10⁻³ A/m² = 0.1 µA/cm².
