how long is the cable?

The measurements are approximately 12 inches from connection tip to the other tip. That being said I have measured 3 others that I have and they are a few millimeters off from each other. Some a little longer and some being a 1 or 2 mm shorter, I do Recommend these cables. I have always had good experience using them but I always check to make sure that all the solder joints are tight by gently tugging on each connection to check for continuity.
