A/cm² = mA/cm² × 0.001
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.
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.
