Length of Wire (l ):     Inches
Diameter of Wire (a) :     Inches
Electrical TechnologyElectrical Technology  
Inductance:     µH

Good to know*
L = K x a x [ { ln (2l / a) } – 0.75]
L = Inductance in µH
K = 0.00508 (dims in inchs)
= 0.0002 (dims in mm)
= wire radius (inches or mm)
l = wire length (inches or mm)
ln = Natural Logarithm
= 2.303 * Common Log [base 10] 
L= 0.00508xbx (log (2xb/ (w+h)) +.5+0.2235x (w+h)/b)
L= 0.00508xbx (log (2xb/a)-0.75)
L = Inductance in µH
b= wire length
a = wire diameter
This is calculation is based on assuming the electrode or straight wire in Free Space.

  1. Your calculation does not take into account the resistivity of the wire material, aluminium, copper, silver, etc. which will also have an effect on the inductance value.
