MA/m² = abA/cm² × 0.1
About Abamperes per square centimetre
The abampere per square centimetre (abA/cm²) is the current density unit of the CGS-EMU system, equal to 10 A / 10⁻⁴ m² = 10⁵ A/m². The abampere (= 10 A exactly) was the CGS-EMU base current unit before SI adoption; in EMU notation Ampère’s law uses J in abA/cm² and magnetic field in gauss without additional conversion factors. 1 abA/cm² = 10⁵ A/m² = 10 A/cm².
About Megaamperes per square metre
The megaampere per square metre (MA/m²) equals 10⁶ A/m², encountered in lightning channel physics and pulsed-power fusion devices. Peak current density in a lightning return-stroke channel is 10-100 MA/m²; plasma current sheets in z-pinch implosions reach 1-100 MA/m²; liquid-metal MHD pumps in fast reactors operate at 0.5-5 MA/m². 1 MA/m² = 10⁶ A/m² = 10³ kA/m².
