What does AWG mean in cable sizes?
Conversely, a large number in AWG equates to a very small number of mm. AWG sizes do not fit perfectly into mm or inches, so you may need to round up or down when safe to do so. Cable sizes (including AWG) refers to the size of the conductor, not the total thickness of the cable including sheathing etc.
How are diameter and area rounded to the nearest AWG?
* Diameter and area values are rounded to fit the nearest AWG value. ** The diameter and area of the conducting wire without isolation. When calclating AWG from diameter or cross sectional area, the diameter and cross sectional area are rounded to the nearest AWG equivalent values.
