Conversion Formula
mA/cm² = A/ft² × 1.076391042
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 Milliamperes per square centimetre
The milliampere per square centimetre (mA/cm²) equals 10 A/m², the dominant current density unit in electrochemistry and fuel-cell engineering. Proton-exchange membrane fuel cells produce peak power at 1000-2000 mA/cm²; hydrogen electrolysers run at 200-2000 mA/cm²; industrial chlor-alkali cells operate at 200-400 mA/cm². 1 mA/cm² = 10 A/m² = 10⁻³ A/cm².
