Ohms per Inch of different gauge wire

[VAPERMAN]

Found this a while ago on a forum. Very easy to reference when you want your ohms as exact as possible. This shows your ohms per inch of different gauge wires. Enjoy

What a great chart!!!

Brian!! Remember when you used to post battery charts and still had to decipher for me? Do you do wire?
