Enter a size in AWG, SWG, mm or mm² to get the equivalent in all other systems, plus cross-sectional area, current rating and resistance per metre -the figure needed when winding transformers or calculating cable voltage drop. · in General
Enter a size in AWG, SWG, mm or mm² to get the equivalent in all other systems, plus cross-sectional area, current rating and resistance per metre -the figure needed when winding transformers or calculating cable voltage drop.


How to use
What it's for
AWG ↔ SWG ↔ mm ↔ mm² ↔ mil, with current rating and resistance per metre.
You enter
- A size in any of those systems.
You get
- The equivalent in all the others, cross-sectional area, current rating, and resistance per metre — the figure you need when winding transformers or working out cable drop.
