Convert Milliamperes per square centimetre to Gigaamperes per square metre
Convert Milliamperes per square centimetre (mA/cm²) to Gigaamperes per square metre (GA/m²) instantly and accurately.
Conversion Formula
GA/m² = mA/cm² × 1.000000000e-8
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 Gigaamperes per square metre
The gigaampere per square metre (GA/m²) equals 10⁹ A/m², the extreme scale for thermonuclear plasmas and ultra-fast pulsed discharges. Current density in the compressed plasma of a z-pinch at peak compression is 1-100 GA/m²; field-emission current density from a sharp metallic tip at the Fowler-Nordheim threshold is ≈1-10 GA/m². 1 GA/m² = 10⁹ A/m² = 10³ MA/m².
