Hi Dave,

The factor 10^-7 needs to be 10^-6 for the equation to work...  Dontcha
just hate that! :o)))  Your equation here will still give an answer off by
a factor of 1/10th...

The units are kind of interesting.  Normally inductance is in the base
units of:

kg-m2/s2-A2 which matches you units!  So if you can get a rock solid
derivation together that the heavy math types would accept, it would be
very interesting!!

Cheers,

	Terry
