µA/cm2\text{µA/cm}^{2}

microampere per square centimeter

Current density

One microampere per square centimetre, equal to 0.01 A/m². It is the unit of laboratory corrosion measurement, where the corrosion current densities that matter are small and a polarisation-resistance instrument reports in exactly this range.

Watch out: A corrosion current density of 1 µA/cm² corresponds to roughly 0.0116 mm/yr of penetration in iron — slow, but a decade of it is a tenth of a millimetre off every surface.
