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 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.
