transmission line

(OP)
the inductive reactance X of any transmission line can be witten as below.

X = 0.004657*f*log(Ds/GMR) ohm/mile/conductor

Where Ds - equvallent spacing in feet
      GMR - Geometric mean radius in feet
        f - frequency in Hz

Now the unit mile is to be changed as km (ie reactance in ohm per km per conductor). whatis the procedure. please help me.  Can I directly multiply the conversion factor  (1/1.609344).

since 1 mile = 1.609344 km

RE: transmission line

     Yes. You'r right
