I  probably posted something about this. The inductance of a straight 
wire is  around 1 nH per millimeter (not cm), or
1 uH/m (the first value exact  for  a 1 mm wire with ~0.01 mm of 
diameter, the last value exact for  a 1 m wire with ~1.3 cm of diameter).
Long, thin wires have more  inductance. Short, thick wires have less.
The capacitance of a sphere (or  practically any shape with similar size) 
far from other objects is 1.11265  pF/cm of radius.

Hi Antonio,
 
If 1uH/m is correct, then on page vi of Richard Hull's book,
"Tesla Coil Builder's Guide to CSN", there seems to be  a mistake.
