Jump Lead Cable Diameters ?
Now you have me thinking mine are about 6 feet in length, when I get them back I will check the O.D. of the cable in my mind it was around half an inch including insulation so I guess they must be nearer the 9-10 mm mark. As they are so old could they be a higher copper grade with more strands?

Don't forget that the cable size Rick is mentioning, is given in cross sectional area, so a 50mm2 cable has a conductor of 8mm diameter, and then the insulation on something like welding wire will take it out to about 13mm outside diameter.
6mm diameter conductor sized wire will be the equivalent of about 30mm2. |

It's not as simple as that, as the conductor is made up of multiple round strands, and in order for the cable to bend, they need to not be too tightly packed together. It's also affected by the size and how many individual strands there are, that's why you buy cable by area, not the conductor diameter and why the conductor size is bigger than the logical size using that calculation.
