Type a value in A/m² to get it in A/mm² instantly.
4×10⁻⁶A/mm²
Nothing on our list is smaller: a plating bath is 75× higher. Through ordinary 2.5 mm² cable that is 1×10⁻⁵ A.
Convert the other way: A/mm² to A/m²

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