4,000,000A/m²
That's 1.33× as hard-worked as a transformer winding, while house cable at full load is 2× higher. Through ordinary 2.5 mm² cable that is 10 A.
Convert the other way: A/m² to A/mm²

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/mm² to A/m²
To convert amperes per square millimeter to amperes per square meter, multiply by 1,000,000.
Example: 4 A/mm² × 1,000,000 = 4,000,000 A/m².
In the other direction, 1 A/m² = 1×10⁻⁶ A/mm².
