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 Femtoamperes per square metre
The femtoampere per square metre (fA/m²) equals 10⁻¹⁵ A/m². Leakage current density through the dielectric of a high-quality capacitor at rated voltage is in the fA/m² range; dark current density in cooled CCD image sensors at -30 °C is around 1-10 fA/m²; radiation-induced leakage in neutron-irradiated MOS gate oxides is measured in fA/m². 1 fA/m² = 10⁻¹⁵ A/m² = 10⁻³ pA/m².
