0.0062A/mm²
That's 21× as hard-worked as a plating bath, while a hydrogen fuel cell is 1.94× higher. Through ordinary 2.5 mm² cable that is 0.0155 A.

How hard is the conductor working?
Wiring figures are rough guidance only. Real cable ratings depend on insulation, bundling and air temperature, so follow your local wiring rules.
The math
How to convert A/in² to A/mm²
To convert amperes per square inch to amperes per square millimeter, multiply by 0.00155.
Example: 4 A/in² × 0.00155 = 0.00620001 A/mm².
In the other direction, 1 A/mm² = 645.16 A/in².
