About Amperes per square centimetre
The ampere per square centimetre (A/cm²) equals 10⁴ A/m², the standard current density unit for power electronics, arc physics, and high-performance batteries. Bipolar junction transistor saturation current density is 0.5-5 A/cm²; vacuum arc contact spots on copper carry 100-1000 A/cm²; fast-charge lithium-ion cathodes support up to 0.05 A/cm². 1 A/cm² = 10⁴ A/m² = 10 kA/m².
About Milliamperes per square metre
The milliampere per square metre (mA/m²) equals 10⁻³ A/m². Cathodic protection current density applied to reinforced concrete structures is 2-20 mA/m²; faradaic current density during slow anodic dissolution of iron in dilute H2SO4 is 1-100 mA/m²; exchange current density of the oxygen reduction reaction on platinum is ≈2 mA/m². 1 mA/m² = 10⁻³ A/m² = 0.1 µA/cm².
