   I recommend that anyone seriously interested in calculating 
inductance get a copy of  the book by Frederick Grover, Inductance 
Calculations: Working Formulas and Tables, Dover Publications, Inc., 
New York 1946.  Used copies are still available if you dig around.  A 
lot of the material here is about the same as in the much older BS 
C74 and is in more convenient form.  There is a useful procedure for 
calculating inductance in a letter from Richard Lundin in the PROC. 
IEEE, V75 #9, 9/85, PP1428-1429.  Claimed to be accurate to about 3 
ppm for solenoids of any form factor.  If anyone is really seriously 
interested I can send him an Excel worksheet which compares several 
different familiar inductance formulae to the values given by 
Lundin's expressions.

   Wheeler's two formula are still plenty accurate for any hobby 
work that I can think of.
