About Picoamperes per square metre

The picoampere per square metre (pA/m²) equals 10⁻¹² A/m². Reverse-bias dark current density in silicon p-n junctions at room temperature is 1-100 pA/m²; gate leakage current density in sub-22 nm CMOS transistors spans pA/m² to nA/m²; dark current density of cooled InGaAs photodiodes is in the pA/m² range. 1 pA/m² = 10⁻¹² A/m² = 10⁻³ nA/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.
