Convert Amperes per square inch to Milliamperes per square centimetre
Convert Amperes per square inch (A/in²) to Milliamperes per square centimetre (mA/cm²) instantly and accurately.
Conversion Formula
mA/cm² = A/in² × 155.00031
About Amperes per square inch
The ampere per square inch (A/in²) equals 1 / (0.0254)² A/m² ≈ 1550 A/m², used in US power semiconductor datasheets and electroforming specifications. JEDEC JESD22 and IPC standards specify maximum allowable current density in bond wires and copper interconnects in A/in²; electroforming of micro-components targets 0.5-5 A/in². 1 A/in² ≈ 1550 A/m² = 0.155 A/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.
