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 Microamperes per square metre
The microampere per square metre (µA/m²) equals 10⁻⁶ A/m². Corrosion current density of carbon steel in neutral deaerated water is 0.1-100 µA/m²; exchange current density of the Zn/Zn2+ electrode is ≈20 µA/m²; cathodic protection criterion current density for buried steel pipelines in low-resistivity soil is 2-20 µA/m². 1 µA/m² = 10⁻⁶ A/m² = 10⁻³ mA/m².
