Nanofarads per kilometer to picofarads per foot
Type a value in nF/km to get it in pF/ft instantly.
4.938pF/ft
That's 1.8× as capacitive as an overhead power line, while Cat 5e network cable is 3.2× more capacitive. A 30 m run of it adds about 0.486 nF.
What it means
How capacitive is that cable?
Conductor-to-shield (or conductor-to-conductor) capacitance as data sheets give it.
The math
How to convert nF/km to pF/ft
To convert nanofarads per kilometer to picofarads per foot, multiply by 0.3048.
Example: 16.2 nF/km × 0.3048 = 4.93776 pF/ft.
In the other direction, 1 pF/ft = 3.28084 nF/km.
