About Femtoamperes per square metre
The femtoampere per square metre (fA/m²) equals 10⁻¹⁵ A/m². Leakage current density through the dielectric of a high-quality capacitor at rated voltage is in the fA/m² range; dark current density in cooled CCD image sensors at -30 °C is around 1-10 fA/m²; radiation-induced leakage in neutron-irradiated MOS gate oxides is measured in fA/m². 1 fA/m² = 10⁻¹⁵ A/m² = 10⁻³ pA/m².
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.
