milliampere per square meter
One milliampere per square metre, equal to 0.001 A/m². It is the cathodic-protection design unit: the current a structure needs per unit of wetted area to hold its potential in the protected range.
Watch out: Design current densities are conventions drawn from experience with a given environment and coating condition, not physical constants. A figure for bare steel in cold seawater does not transfer to warm brackish water or to a coated structure.
