Example
IBM LAN cables (STP/UTP) are normally AWG-22 cables. When you measure
on such a (disconnected) cable 10.9 Ohm (on each pair), you can consider
that this cable will have an appr. length of 100 meters.
10.9 / 5.44 = 2 * 100 meter AWG-22 cable (total 200 meters)
because you measure 2 wire's, you have to divide by 2 = 100 meters.
