About Statamperes per square centimetre
The statampere per square centimetre (statA/cm²) is the current density unit of the CGS-Gaussian system, equal to 1000/c A/m² where c = 299 792 458 m/s, giving ≈3.336 × 10⁻⁶ A/m². In Gaussian electrodynamics the statA/cm² is the natural current density when fields are in statV/cm; it appears in plasma physics texts using Gaussian units. 1 statA/cm² ≈ 3.336 µA/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.
