You need to know more than the length, the cross section is needed too. It's really micro mhos per centimeter per square centimeter.

I've never seen conductivity measurements that refer to area.

Then you've not been looking at the right measurements.

Resistance goes down the more area of conductive material you have.

Think parallel resistance measurements.

Total Ohms = 1/R1 + 1/R2
