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 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.
