Enter the required values of length of wire and diameter of wire in inches and click on calculate. Result will display the value of Inductance in µH.
Formula and Equations for Inductance Calculator
L = K x a x [ { ln (2l / a) } – 0.75]
Where;
- L = Inductance in µH
- K = 0.00508 (dims in inchs) = 0.0002 (dims in mm)
- a = wire radius (inches or mm)
- l = wire length (inches or mm)
- ln = Natural Logarithm = 2.303 * Common Log [base 10]
Also;
L= 0.00508 x b x (log (2 x b/ (w+h)) +.5+0.2235 x (w+h)/b)
And;
L= 0.00508 x bx (log (2 x b/a)-0.75)
Where:
- L = Inductance in µH
- b= wire length
- a = wire diameter
This calculation is based on assuming the electrode or straight wire in Free Space.

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.
