Amperes per square millimeter to amperes per square centimeter
Type a value in A/mm² to get it in A/cm² instantly.
400A/cm²
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/cm² to A/mm²
What it means
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/cm²
To convert amperes per square millimeter to amperes per square centimeter, multiply by 100.
Example: 4 A/mm² × 100 = 400 A/cm².
In the other direction, 1 A/cm² = 0.01 A/mm².
