About Abamperes per square centimetre
The abampere per square centimetre (abA/cm²) is the current density unit of the CGS-EMU system, equal to 10 A / 10⁻⁴ m² = 10⁵ A/m². The abampere (= 10 A exactly) was the CGS-EMU base current unit before SI adoption; in EMU notation Ampère’s law uses J in abA/cm² and magnetic field in gauss without additional conversion factors. 1 abA/cm² = 10⁵ A/m² = 10 A/cm².
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.
