Convert Amperes per square metre to Milliamperes per square centimetre
Convert Amperes per square metre (A/m²) to Milliamperes per square centimetre (mA/cm²) instantly and accurately.
Conversion Formula
mA/cm² = A/m² × 0.1
About Amperes per square metre
The ampere per square metre (A/m²) is the SI coherent unit of current density, defined as 1 A flowing through 1 m² cross-section. Electrolytic copper plating baths operate at 200-500 A/m²; photovoltaic short-circuit current density of silicon solar cells at AM 1.5G is 35-42 A/m²; cathodic protection of bare steel in soil applies 10-50 A/m². 1 A/m² = 0.1 mA/cm².
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.
