Oops!  I got mixed up in the notes sequence.
Somebody else posted the diameters.  In general,
if N = the thread number, then its diameter D, in
inches, is

D = .013*N + .060

 My book says that the formula for ANF sizes below 1/4" is

	a x b
 where a is nominal size
           b threads per inch

and the nominal diameter is  (Number x 0.013) + 0.060 inches

Not sure what American inches are. Think it's a system used in 
the US of A and Nigeria!  :-)

Long ago America and Great Britain adopted the Canadian inch which is
defined as 25.4mm.
